It's been 20 years since world-renowned folklorist Iona Opie and beloved illustrator Rosemary Wells (who Opie firmly believes is Mother Goose's second cousin) published the ultimate--and award-winning--nursery rhyme collection My Very First Mother Goose. With this anniversary edition (sporting a fetching new pale-yellow cover), another generation of young children will clap their hands, wiggle their toes and sing-song along to 60 "eccentric, funny, goluptious, haphazard" rhymes, from the familiar ("Hey diddle, diddle,/ the cat and the fiddle...") to the obscure ("Bat, bat,/ Come under my hat,/ And I'll give you a slice of bacon...."). Wells's watercolors, as always, are cozily adorable. Toddlers will gleefully point out the cheese-nibbling mouse at the feet of a happily snoozing cat in plaid bathrobe in "Dickory, dickory, dock," or perhaps they'll notice how the grandfather clock looks like it has cat ears or how the wallpaper buzzes with ace-flyer pigs. Every household needs this book. --Emilie Coulter, freelance writer and editor

With Los Pollitos/ Little Chickies, author-illustrator Susie Jaramillo took a well-loved Spanish-language nursery rhyme and turned it into an endearing, reversible, lift-the-flap, accordion-style board book--one side all in Spanish and one side translated into English, except for the "pío" (cheep) sounds, which are too cute (and onomatopoeic) not to be in both versions.

"Los pollitos dicen/ ¡pío! ¡pío! ¡pío!" ("Little chickies squeal ¡pío! ¡pío! ¡pío!") Lift up the cracked egg to reveal a hatched chick peeping away. The story is simple: chicks cheep until their mother fetches them some corn from the field, feeds them, then snuggles up with her babies under her wing "where they'll stay,/ until another day."

This interactive, intuitively designed, cheerfully illustrated book (with slipcase) is charming on its own, but becomes even more memorable when readers hear it sung: the small print in the back reveals how to download the app for "Canticos: Los Pollitos." ¡Pío! ¡Pío! --Karin Snelson, children's & YA editor, Shelf Awareness

Flora, a young girl fluttering a pretty fan, befriends one extravagantly plumed peacock. When another peacock expresses his disapproval, Flora graciously approaches him, but now the first bird is jealous. Friendship is a dance. What's a third wheel to do?

Following Molly Idle's Caldecott Honor-winning Flora and the Flamingo and Flora and the Penguin, this eye-catching and lyrical pop-up book is so evocative, so emotive, it's almost a surprise to realize it's entirely wordless. All the "speaking" is done with facial expressions, body language and visual plot action. One can almost hear the peacock muttering a skeptical "hmm" as Flora curtsies a greeting, and then huffing a resentful "hmph!" Young readers (gently, please!) lift the flaps to see haughty bird faces, peacock tails in full blue-green-yellow glory and--most spectacular of all, in a giant origami-like gatefold--the moment when peace and friendship win the day. --Emilie Coulter, freelance writer and editor

Megalopolis is an architecturally magnificent city, admired by all: "One day, there was even a visitor from another galaxy." So begins the story of Megalopolis, an extraordinary, eccentric book that must be read on the floor because the thick paper pages unfold into a fabulously, ridiculously long, 10-foot scroll--a stunning vertical cityscape.

A green alien visitor arrives in his bubble-domed flying saucer and lands on a rooftop. The mayor "straightaway declared a holiday so that the entire city could throw a grand party to welcome him." Parades, fireworks atop an "old, dormant volcano," and a "huge game of hide-and-seek in the Chinese Gardens" ensue. A big tea party honors the new "Ambassador of Outer Space," but he is "overpowered by a praline," perceived to be dead, and placed on "a raft heaped with flowers." A mermaid saves his life with "a good hard pat on the back," and they fall in love at first sight. Deliciously odd and truly not-to-be-missed. --Karin Snelson, children's & YA editor, Shelf Awareness

Rose-colored glasses expose quite the menagerie in the irresistible, jumbo-sized Illuminature, created by Italian designer Carnovsky and written by Rachel Williams (Atlas of Adventures; Atlas of Animal Adventures). Ten of the world's most biodiverse environments--and 180 animals--are "illuminated" by a "magic" three-colored lens strip (snugly stored in a pocket on the inside front cover) that makes creatures and plant life pop into view from several overlaid, multi-colored pages. Look through these cardboard-framed lenses (red for daytime animals, blue for nighttime/twilight animals and green for habitat) on the "Observation Deck" pages to find the rearing blue wildebeest of the Serengeti plains, the howling Eurasian wolf of the East Siberian taiga and the bizarre crocodile icefish of the Weddell and Ross Seas. Then turn to the "Species Guide" that visually highlights and briefly describes each creature. Readers of all ages will fight over this one like two chattering Sonoma chipmunks. --Emilie Coulter, freelance writer and editor

Alsace-born Tomi Ungerer, winner of the Hans Christian Andersen Award for children's literature, was called "a spectacular graphic genius" by the illustrious Maurice Sendak. Phaidon has outdone itself with this lovingly designed, slip-cased single volume that includes eight of Ungerer's picture books: well-known favorites (The Three Robbers, Moon Man, Otto), recent works (Fog Island) and forgotten treasures (Zeralda's Ogre, Flix, The Hat and Emile), some out-of-print for decades. Fans will also get the inside scoop on several of his unforgettable books via an exclusive interview, an author letter, photographs and many "making of" storyboards and drawings, including some fabulous pencil sketches on the endpapers. Ungerer's picture books are splendidly quirky explorations of human nature and also, as he says, often "campaign against social injustice, prejudice and war." A treasury indeed. --Karin Snelson, children's & YA editor, Shelf Awareness

E.T.A. Hoffman's 1816 Nutcracker shines like tinsel in this lively version based on the landmark ballet choreographed by George Balanchine for New York City Ballet. (Fun fact: 105 costumes appear onstage in each performance!)

On Christmas Eve, Marie receives a special gift from her beloved godfather: a Nutcracker "dressed as a handsome soldier with a white beard." That very night, Marie wakes to find her Christmas tree grown impossibly large, and stranger still, the Nutcracker comes to life. He defeats the menacing Mouse King, transforms into a handsome Prince, and leads Marie out into the snowy night. The Prince and Marie embark on a fantastic journey in a "cozy walnut boat" to the Land of Sweets where the Sugarplum Fairy honors them with wondrous entertainment by her subjects, including Mother Ginger, who dances with tiny clowns beneath her skirt. Argentina-born Valeria Docampo's luminous illustrations evoke the breathtaking splendor of New York City Ballet's Nutcracker, still performed every winter at Lincoln Center. --Lynn Becker, blogger and host of Book Talk, a monthly online discussion of children's books for SCBWI

Christmas in the Barn by Margaret Wise Brown (Goodnight Moon; The Runaway Bunny) was first published in 1952 as a lyrical narrative with wood-cut illustrations by Barbara Cooney. Here, Brown's appealing picture book about the Nativity (baby Jesus is only identified as "the newborn babe") is reissued with cheerful, roughly textured paintings of a sun-soaked desert landscape and a menagerie of personality-loaded sheep, donkeys, camels, horses and mice (even a cat and dog!) in oil paint, pastel, pencil and marker by the late Anna Dewdney (the Llama Llama books). "In a big warm barn in an ancient field/ The oxen lowed, the donkey squealed,/ The horses stomped, the cattle sighed,/ And quietly the daylight died/ In the sunset of the west." A lost couple walks into that barn and is welcomed by all the curious animals... until "the first wail of the newborn babe reached the night/ Where one great star was burning bright." A charming, truly preschooler-friendly addition to the Christmas picture-book shelf. --Karin Snelson, children's & YA editor, Shelf Awareness

"Once upon a time, there lived a kind and beautiful princess named Izta. Even though she was the daughter of an emperor, she loved to spend time with the people who grew corn in the milpas." So begins Mexican author-illustrator Duncan Tonatiuh's (Rancho Rabbit and the Coyote; Funny Bones: Posada and His Day of the Dead Calaveras) retelling of one of his country's most cherished legends about two young people in love. Sadly, Izta and her beloved warrior Popoca were betrayed and fated to spend the rest of eternity as two side-by-side volcanoes: Iztaccíhuatl, who still sleeps, and Popocatépetl, "who spews ashes and smoke from time to time, as if attempting to wake his sleeping princess." (These real volcanoes are located about 40 miles southeast of Mexico City.) Tonatiuh's warmly hued, textured illustrations are inspired by the 11th-century Mixtec warrior codices, "where people and animals are always drawn in profile." A touching story of two true hearts. --Karin Snelson, children's & YA editor, Shelf Awareness

Three-quarters of a century has passed since George, "a good little monkey and always very curious," began winning the hearts of readers worldwide. Created by German husband-and-wife team Margret and H.A. Rey, Curious George embarked on a series of misadventures, such as swallowing a puzzle piece, floating away under a bunch of balloons and rescuing an escaped bear cub. In addition to the seven original tales--Curious George, Curious George Takes a Job, Curious George Rides a Bike, Curious George Gets a Medal, Curious George Flies a Kite, Curious George Learns the Alphabet and Curious George Goes to the Hospital--this bright yellow volume includes an access code to free downloadable audiobooks, a new illustrated biography of the Reys and an original illustrated map of Curious George's world. Fans from every generation will love having this classic on their shelves. --Emilie Coulter, freelance writer and editor

Armstrong is the inventive, lavishly illustrated history of a 1950s-era New York City mouse who is fascinated by the moon, a companion book to German author-illustrator Torben Kuhlmann's Lindbergh: The Tale of a Flying Mouse.

Every night, this little mouse gazes through his "iron tube full of glass lenses" at the starry sky. Though the other mice believe the moon is made of cheese ("as yellow as Gouda, then as white as Camembert"), the little mouse tries hard to convince them it's actually stone. When he receives a mysterious, "mouse-sized" invitation to the Smithsonian, he hops on a train to Washington, D.C. In a basement underneath galleries of "human inventions," the little mouse discovers artifacts of the long-forgotten history of mouse aviation and vows to be the first mouse on the moon. So, on July 21, 1969, when the first humans walked on the surface of the moon, one extraordinary little mouse had already beaten them there! A whimsical take on space-travel history. --Lynn Becker, blogger and host of Book Talk, a monthly online discussion of children's books for SCBWI

Award-winning British artist Jim Kay (Patrick Ness's A Monster Calls) illustrated J.K. Rowling's Harry Potter and the Sorcerer's Stone in 2015. Here, he follows up that wildly successful venture (Rowling-approved!) with 115 more of his lavish, atmospheric, full-color paintings in an unabridged, jacketed hardcover edition of Harry Potter and the Chamber of Secrets, complete with orange-ribbon bookmark and an easy-to-read two-column format. Kay brings Harry Potter's second year at Hogwarts to dramatic life, including the bug-eyed house-elf Dobby, a rousing full-bleed spread of the flying car, Knockturn Alley, the giant Hagrid, Moaning Myrtle, the insufferably self-centered professor Gilderoy Lockhart and much, much more. A smashing gift for Potter fans of all ages. --Karin Snelson, children's & YA editor, Shelf Awareness

Sensitive, nature-loving readers will thrill to this adventure story written and illustrated by Peter Brown (Mr. Tiger Goes Wild) in his middle-grade debut. ROZZUM unit 7134, a brand-new bipedal robot with a dome-shaped head and glowing eyes reminiscent of the Iron Giant, gets shipwrecked on an unpopulated island and is accidentally activated by curious otters. At first the animals on the island run from "Roz" and call her "the monster." But when the robot adopts an orphaned gosling she names Brightbill, the once-hostile community of wildlife rallies around her as she struggles to feed and shelter her fluffy charge. In time, resourceful Roz cleverly, contentedly adapts to motherhood and the only home she knows, but her Makers have not forgotten her, and they want her back at any cost.

Filled with Brown's terrific, geometric black-and-white illustrations, The Wild Robot combines humor, family ties and an intelligent wilderness survival story for a quirky and thought-provoking romp that will leave readers pondering whether artificial intelligence can give rise to real love. --Jaclyn Fulwood, lead librarian at Del City Public Library, Okla.

If you've been waiting for Jacqueline Woodson's (Another Brooklyn; After Tupac and D Foster) award-winning Brown Girl Dreaming to be released in paperback, your moment has arrived.

Originally published by Nancy Paulsen Books, Brown Girl Dreaming--Woodson's memoir in verse about growing up as an African American girl in the 1960s and 1970s in Ohio, S.C., and Brooklyn, N.Y.--won the 2014 National Book Award for Young People's Literature; a 2015 Newbery Honor and a 2015 Coretta Scott King Award. As Shelf Awareness reviewer Kyla Paterno wrote, "Woodson offers readers an accessible, first-hand look at African American childhood during decades of tremendous turmoil and change.... [Her] beautiful words and fantastic characterization make this story a true gem." This handsome 2016 paperback edition includes seven new original poems by Woodson. --Karin Snelson, children's & YA editor, Shelf Awareness

Any tech-minded sort will flip over DK Publishing's Super Cool Tech. Designed to look like a laptop with a silver cover, metallic-edged pages, rounded corners and landscape orientation, this dynamic exploration of tech developments and inventions--present and future--overflows with excellent full-color photos, graphics and intriguing facts. Curious about ice hotels? (Hint: it involves "snice," a slushy mixture of snow and ice.) How about the Bio-Bus (runs on human waste), teleportation (scientists have already teleported small amounts of light energy 89 miles!) or colorful musical jellies (they change the electric field of a capacitor board, creating a sound that varies according to the shape, color and saltiness of the jelly)? The answers are all here.

Seven sections--Play, Move, Construct, Power, Live, Future and Reference--cover super-cool technology advances in the world today including smartwatches, hoverboards, 3-D printers, drones, underwater hotels and driverless cars, providing just enough information to tantalize and inspire. --Emilie Coulter, freelance writer and editor

Animals are fascinating, sure, but former reference librarian and debut author Brooke Barker also finds some aspects of their lives "incredibly sad": "Sea turtles are majestic, but did you know that they never meet their parents, or that octopi don't have friends...? Animals, it turns out, are just as complicated and conflicted as we are." It must be said up front: Sad Animal Facts is really funny, considering. In the "Reptiles & Amphibians" section, a featured fact is: "Fire salamanders eat their siblings." The melancholy cartoon fire salamander is thinking, "being an only child has a terrible aftertaste." In "Mammals," readers discover that "Hippos attract mates by peeing." "Another great reason to be single," says the hippo. In "Marsupials," "Koalas are only social for 15 minutes a day." The koala says, "This is a really fun party but I have to leave immediately." Even with its benign Tinder joke, the content of Sad Animal Facts is largely PG-13. A coffee-table hoot. --Karin Snelson, children's & YA editor, Shelf Awareness

Marissa Meyer's bestselling Lunar Chronicles are imaginative, futuristic retellings of classic fairy tales, and this boxed set collects hardcover editions of Cinder, Scarlet, Cress, Winter and Fairest. Meyer's debut YA novel, Cinder, introduces a self-reliant, 16-year-old cyborg Cinderella who cobbles together her own coach from a junkyard car and is the breadwinner for her adoptive family. As Meyer explained in a 2011 Shelf Awareness interview, "Book two is Scarlet, and it's based on Little Red Riding Hood. Book three is Cress, inspired by Rapunzel. And the fourth, Winter, is based on Snow White. We'll continue to follow Cinder as she puts together the pieces of her past and how to defeat Levana [ruler of Luna]. They'll have separate, parallel story lines, and Cinder's path will cross with theirs. They'll form one group with a mission to defeat Queen Levana and stop the war." In the stand-alone Fairest, Meyer reveals the background of the villainous Queen Levana. Meyer fans present and future, rejoice! --Karin Snelson, children's & YA editor, Shelf Awareness
