Abi Maxwell's (Lake People) second novel, The Den, features cleverly interwoven stories about two pairs of sisters on the same land 150 years apart.

In modern-day New England, sisters Henrietta and Jane, ages 15 and 12, live in an old farmhouse on the outskirts of a small town. Jane is distressed when Henrietta starts to distance herself from her family after meeting a boy from town, and she follows the young couple, hoping to get close to her sister again. One night, Henrietta disappears without a trace, leaving her parents and Jane distraught and stunned.

On the same property, 150 years earlier, Elspeth Ross lives in a small cabin in the woods with her husband, who works at the local mill, and their three sons. She hated to leave her beloved younger sister, Claire, and her parents behind in Scotland, but Elspeth was forced to move with her new husband to hide her pre-wedding pregnancy. After a series of violent incidents involving the mill owner, Elspeth and her family leave town without a trace.

These two stories are intricately connected, not only by the locations and similarities but also by a fantastical story about the Rosses' disappearance in a local book that Henrietta and Jane's father read to them over and over. In both cases, the older sisters vanish under mysterious circumstances, while their younger sisters pine for them. This intriguing story of two families separated by time also explores desire, shame and secrets. --Suzan L. Jackson, freelance writer and author of Book By Book blog

Khai Diep is certain he has a stone heart, one that can't feel love or sadness. During his cousin Andy's funeral, Khai remains dry-eyed. It doesn't bother him too much, though. Isn't it a good thing grief can't touch him? Who wants to wail like his aunties? Besides, he likes being alone with his routines, not dealing with messy emotions.

But his mother has other ideas. She knows Khai processes emotions and social cues differently because he has autism. She goes to Vietnam to choose him a bride and meets My, a feisty young single mother who cleans hotel bathrooms. Khai's mother gives My a startling offer: she'll pay for My to spend the summer with Khai in California and get him to marry her. Other than the possibility of a better life for her and her young daughter, My has another reason for accepting the offer: she wants to find her American father, whom she's never known.

My renames herself Esmeralda, and her plan to win over Khai leads to unexpected discoveries about herself and what she wants from life.

Helen Hoang's The Bride Test is even more affecting than her breakout hit, The Kiss Quotient. With heart and humor, she humanizes people who are routinely marginalized, and Esme especially is someone to root for--a woman born into poverty who knows her value even when the world looks down on her. By the time Hoang says in the author's note that Esme is based on the author's own mother, a war refugee who became a successful businesswoman, readers might find their eyes aren't dry at all. --Elyse Dinh-McCrillis, blogger at Pop Culture Nerd

Ella Kendall returns to her hometown of Three Rivers, Tex., a little better off than she started. After being raised in the foster care system, she's been taking and cherishing what she can get: her old, beat-up car, the rundown house she inherited and the memory of a stolen kiss from Luca Prince in high school. The Princes are a dynasty in Cimarron County--rich, famous and a staple of the community. Ella has no idea why Luca kissed her that night, or why he's decided to notice her when she moves back home.

Julia London (the Highland Grooms series) could have easily put Luca in the billionaire bad boy role, but instead creates a well-developed character. Luca has had a comfortable upbringing and wants for nothing. However, his family willfully ignored his dyslexia while he was growing up, leaving him functionally illiterate as an adult. His drive to become a conservationist and revert his family land to wildlife spurs him to learn how to read as an adult. Luca's soft heart for animals and desire to become more than just his money make Ella to fall for him. The majority of the book is fun and lighthearted, but the last quarter takes a darker turn as Ella deals with her toxic relationship with Stacy, a friend from the foster system. However, London steers the story back to the hopeful and delivers a satisfying happily-ever-after. --Amy Dittmeier, adult services librarian, Brookfield Public Library, Ill.

Lorene Cary (If Sons, Then Heirs) shares a heartfelt, multifaceted story of caring for her "Nana Jackson," her paternal grandmother, during the end of her life. Nana, who lived to be 101 years old, was complex. An African American who could "pass for white," Nana was strong, independent, affluent and elegant. She drove fancy cars, went to museums and concerts, doted on Cary and generously established a scholarship fund for black students. Nana could also be tough; she demeaned her husband and was a no-nonsense landlord.

Nana's life was not easy. She was raised with four siblings by their widowed father and lived through many health crises and a serious car accident late in life. Nana and Cary's father, whose bond once "seemed inseparable," also stopped speaking to each other for many years.

Approaching her 100th birthday, Nana--a widow struggling to live on her own in a now-unmanageable house in suburban New Jersey--began to suffer from degenerative heart disease. When she could no longer care for herself, Cary and her second husband, a minister, arranged to take Nana in at their rectory in Philadelphia. This arrangement revealed an ornery and demanding grandmother who tested Cary's patience and love amid Nana's complicated end-of-life care.

The last year and a half of Nana's life becomes fertile literary ground for Cary to mine her memories and her family's history in order to pull Nana's remarkable life--and her own--sharply into focus. --Kathleen Gerard, blogger at Reading Between the Lines

There may be no more recognizable person than three-time World Heavyweight Boxing Champion Muhammad Ali, "The People's Champion." Ali's persona is highlighted by his feats in the ring, quick wit, religious conversion and stance against the Vietnam War. Many books have been written about Ali, including three by his second-youngest daughter, Hana (Ali on Ali). In At Home with Muhammad Ali, Hana Ali changes focus and shares an intimate look at Ali's private moments with his family and what it was like to be the child of The Greatest.

A sentimental softy, Muhammad Ali recorded the goings-on in Hana's childhood home, the tapes part of the legacy he left for his children. Shared at length, transcripts include him "messin' " with his kids, prank calling friends and participating in various political causes, including trying to resolve the Iranian hostage crisis. A practicing Muslim, Muhammad Ali believed that by helping one person he was helping hundreds, and he was known to invite strangers from the street to the house.

A loving family man and father, Ali doted on his kids, making sure all seven of them (from multiple wives and mothers) grew up knowing each other. Hana is open about her father's professional pressures and romantic complications, but also his true love with her mother, Veronica, and the later-discovered letters that shed light on their sad parting. A beautiful, in-depth look at a complex and beloved man, Hana Ali's memoir is also a personal journey of forgiveness and the incredible bond between father and daughter. --Lauren O'Brien of Malcolm Avenue Review

Hannah Paasch, a blogger and Twitter influencer credited with starting the #churchtoo movement and #millenneagram, has turned her snark to good use in Millenneagram: The Enneagram Guide for Discovering Your Truest, Baddest Self, a funny and profane update to the ancient personality typing system of the Enneagram.

Paasch, who calls herself an Ex-vangelical, has updated the Enneagram for the millennial crowd, replacing its spiritual overtones with her brash, insightful look at life today. Millenneagram, "a revamped spin on the Enneagram that helps us be our truest, enough-as-is, bad-ass selves," is sure to make readers laugh and also cringe a little as they recognize themselves in the nine personality types of the Millenneagram. From One ("The Machine") to Four ("The Tortured Artist") to Nine ("The Wallflower"), Paasch offers penetrating glimpses into how personality shapes us and how best to live a mentally healthy life.

Each chapter offers warning signs on disintegration (what direction each type heads when not at their healthiest) and helpful tips for improving integration (moving in a mentally healthy direction). Paasch also breaks down each of the nine types into their three instinctual subtypes: the self-preserving, the social and the sexual. For readers who haven't yet jumped on the Enneagram bandwagon, Paasch offers tools and tips for helping to determine your type. A quirky combination of Unfu*k Yourself and The Road Back to You, Millenneagram is quick and refreshingly honest. --Jessica Howard, bookseller at Bookmans, Tucson, Ariz.

Ultra running (running a race of any distance greater than a marathon) has boomed in recent years. Experts estimate a 1,000% increase in the number of ultra races held around the world each year and, according to ULTRA magazine, the number of ultra finishers in the U.K. jumped from 595 in 2000 to 18,611 in 2017. But why, wondered self-identified "runner-geek" Adharanand Finn (Running with the Kenyans), would anyone want to run that far, that hard and for that long? That's what he sets out to answer in The Rise of the Ultra Runners. He uses his own experience training for--and running--one of the world's toughest ultramarathons to try to understand why this "admirable... courageous... mad and insane" sport has seen such a rise in popularity.

Documenting 18 months of training and 10 ultramarathon finishes, Finn leaves no stone unturned in his journey to understand ultra running. He registers for races of increasing distances (from a 50k to a 100-miler) across varied terrain (the desert, a track loop in London, the mountains of France) and speaks to as many elite participants as he can along the way. While The Rise of Ultra Runners will be most appealing for those who have dabbled in, or been intrigued by, the sport, any reader who has wondered about his or her own limits will revel in Finn's stories of the grit and determination it takes to finish one of these races. After all, as ultra runner Elisabet Barnes told Finn, "It's always interesting to push your boundaries. If you always succeed you don't know where your limits are." --Kerry McHugh, blogger at Entomology of a Bookworm

In How to Raise Successful People: Simple Lessons for Radical Results, Esther Wojcicki offers a direct rebuttal to the prevalent style of intense, overprotective parenting. Reflecting on her own journey as a mother, Wojcicki presents an altogether calmer and more wholesome prescription for effective childrearing.

A teacher for more than 35 years, Wojcicki raised three bright, productive daughters and mentored countless teenagers through her journalism program at Palo Alto High School in California. Forget the pressure-cooker parenting techniques of tiger mothers, she advises. Instead, focus on cultivating self-confidence and independence in children and teenagers. It begins with instilling trust and letting them take risks and make mistakes. Respect for each child's autonomy is essential.

Respectful parenting is supportive but also demanding, because it's important to hold one's child to standards that help them grow and learn. Wojcicki encourages parents to nurture a culture of kindness so that children and teenagers can experience the personal rewards of helping others through selfless acts. Collaboration between parent and child, where each family member contributes to discussions, is also an integral part of Wojcicki's parenting approach.

But it's not just about the children. Parents are urged to reflect on their own childhoods and work through unresolved traumas and challenges to avoid inflicting those same wounds on the next generation. Wojcicki, now a grandmother of nine, cautions against the myth of the perfect parent and wholeheartedly embraces the mistakes she made as a mother. Her best piece of advice? Let go of your parenting fears by forgiving yourself for past errors in judgment and trust in your ability to do right by your children. --Shahina Piyarali, writer and reviewer

Laura Dean has broken up with Freddy Riley three times. This time, Freddy walked in on Laura kissing another girl at a dance. Her friends Eric, Buddy and Doodle comfort Freddy outside the school, where she decides to chug a bottle of liquor (" 'Where did you get Schnapps?' 'Oh my God. I can smell it from here.' "). Couple Eric and Buddy head home, leaving Doodle to take care of the very drunk Freddy. Life proceeds miserably for a bit until Laura shows up at Freddy's doorstep and the two begin dating again.

Freddy can tell that her "nonprofessional advice-giving friends are struggling to muster sympathy for [her] increasingly ridiculous situation," so she writes a series of e-mails to an advice columnist. The e-mails work as the graphic novel's exposition while also giving readers an idea of how Freddy perceives the world. Completely involved with Laura, Freddy realizes she's being a bad friend, but can't seem to break out of the cycle. Doodle is in desperate need of a friend--will Freddy come through for her?

Laura Dean Keeps Breaking Up with Me is almost too real. Mariko Tamaki (This One Summer) and Rosemary Valero-O'Connell get the ache, desire and humiliation of being in a relationship that has moved past love into compulsion. Tamaki's Berkeley, Calif., teens are witty and bright, cracking jokes and holding serious discussions about the age of consent. Valero-O'Connell's pencil, ink and digital illustrations depict the rawness of the teen's emotions, every feeling showing in their faces and postures. Each character is infused with personality: Doodle's quiet shrinking into herself; Laura's sexy self-confidence; Freddy's low self-esteem and indecision. Laura Dean isn't a light read, but it's certainly a true one. --Siân Gaetano, children's and YA editor, Shelf Awareness

"When Aidan was born, everyone thought he was a girl." But his name, his room, his clothes just didn't fit. Aidan realized "he was really another kind of boy": Aidan is transgender. With the help of other families with transgender children, Aidan's family figured things out. Now his parents have announced they are having another child, making Aidan a soon-to-be big brother. As the baby's arrival approaches, he expresses his fears: "I don't want them to feel like I did when I was little, but what if I get everything wrong? What if I don't know how to be a good big brother?" Thoughtfully, his mother explains, "We didn't know you were going to be our son. We made some mistakes, but you helped us fix them." Most fundamentally, "you taught us how important it is to love someone for exactly who they are."

Like Aidan, when author Kyle Lukoff (A Storytelling of Ravens) was born, everyone thought he was a girl; he reveals in his author's note that parts of his own story are "very much like Aidan's." Kaylani Juanita clearly enjoys challenging gender expectations with her digital illustrations. As Aidan explores "different ways of being a boy," Juanita shows him posing in a superhero cape (with cutouts from his discarded dresses) and wearing pink shoes with bows. His wardrobe couldn't be more gender-defyingly fabulous, comprised of a mishmash of stripes, zig-zags, checks and animal prints. Together, Lukoff and Juanita create "a world that supports and believes in [Aidan]," modeling a community that embraces "all different kinds of kids." With insight and empathy, both author and artist encourage and enable young readers to help "create that world." --Terry Hong, Smithsonian BookDragon
