Newbery Medal–winning author Rebecca Stead (When You Reach Me) has a rare gift. She can see into the souls of young people as they begin to grow conscious of how others view them from the outside and how they feel on the inside, and she has the skill to illuminate how they grapple with these gaps and overlaps in perception.

For Bridget ("Bridge") Barsamian, that quest to understanding begins early, at age eight, after she suffers an accident that results in 13 broken bones and a punctured lung. A nurse tells her, "You must have been put on this earth for a reason," and Bridge makes it her mission to discover what that reason is. Now, in seventh grade, one of Bridge's two best friends, Emily, develops "curvy new curves," as Tab's older sister puts it. Tab is the third member of their trio, and dates back the longest as Bridge's friend. Emily suddenly gains attention from boys, Patrick in particular. Emily is also athletic, and even eighth-graders start to say hello to her. Tab, bossy and a bit of a know-it-all, just wants things to stay the same.

Tab wants Bridge to join Human Rights Club with her, but Bridge signs up for Tech Crew. That's where Bridge meets Sherm. The trio's disparate interests could pull the friends apart. But Stead takes the more challenging route as a writer: she explores the work it takes to keep and nurture a friendship when the individuals involved are changing.

The situation grows further complicated when Emily and Patrick begin an innocent text exchange of photos of knees and elbows, and gradually more revealing images enter the mix. Tab becomes convinced that Patrick has let it go too far when a photo of Emily in her bra goes viral and, in a fit of loyalty, she takes matters into her own hands. Emily assures Tab that Patrick is telling the truth--that someone else got hold of his phone and sent the revealing photos to a larger group. Stead carefully keeps the situation contained; the subplot involving the texted photos never dominates the novel. Instead, she mines the situation to explore the nuances of friendship: loyalty and petty jealousy, independence and coercion, and where platonic love spills over into romance.

While Emily and Patrick are getting to know each other, Bridge and Sherm are cementing their friendship. Sherm becomes nearly as close a confidant to Bridge as Tab and Emily. And as friends tease Sherm about Bridge, he thinks, "She was definitely not his girlfriend. But she might be his best friend." So when the texted images go viral, Sherm takes a stand--adding to the author's profound exploration of the intricacies of human relationships.

Stead keeps a balance of levity and gravity through three alternating points of view. The main story arc unfolds through Bridge's third-person perspective; Sherm's story unfolds through a third-person narrative, and through unsent letters to his grandfather, who left his wife (and Sherm's family); and a third perspective comes  via the second-person narrative of a mysterious high-schooler told in a single day, Valentine's Day.

The themes of the other two narratives resonate and reverberate with Bridge's thoughts. After Tab and Emily argue about the texted images, Bridge thinks,  "Suddenly the air felt different. Tab wasn't here with them, on purpose. That had never happened before." Sherm tries to make sense of the departure of his grandfather, Nonno Gio, and remembers his father urging Nonno Gio to return to his native Italy for a visit, to remind him who he was, "Because you've turned into a stranger!" And Sherm recalls his grandfather's reply, "You said that, in a way, you were a stranger to yourself. It scared me." The high-schooler, trying to make sense of the rift she feels between herself and her best girlfriend, Vinny, realizes that although Vinny "made you feel as if you were exactly where you wanted to be, if not exactly who.... Maybe Vinny, your Vinny, was gone."

Stead raises questions about whether a relationship can survive change. If someone makes a mistake, can you forgive the person, if not the act? Can two people reconcile, if they are both willing to process what happened? Or is the change more systemic--has one of you become a stranger? The thing that scares Sherm about his grandfather's observation, that Nonno Gio is a stranger to himself, is that "Sometimes I felt like a stranger to myself too," especially when he holds Bridge's hand. "Is the new you the stranger?" Sherm wonders, "Or is the stranger the person you leave behind?"

It's a question all of the characters ask themselves at some point in Stead's perfectly synchronized novel. The book begins on the third Monday in September of Bridge's seventh-grade year and drives inexorably toward Valentine's Day--the complete day recounted in the high-schooler's narrative, and also Nonno Gio's birthday.

The novel threads together the separate journeys of the seventh-graders, the high-schoolers who orbit around Vinny, and even Nonno Gio. What do you do if you want to stay true to the person inside and the person perceived by outsiders? This is the central human dilemma. To Rebecca Stead's credit, she circles the question in such a way that readers of any age can examine it from a variety of perspectives. She looks at life in funny and profound ways that will allow young readers to come to these questions from multiple entry points, no matter where they are on their own journeys. --Jennifer M. Brown

In Newbery Medalist Rebecca Stead's new novel, Goodbye Stranger, Bridget Barsamian suffered a life-threatening accident at age eight that changed not only her, but the lives of those around her. Something a nurse said stayed with her: "You must have been put on this earth for a reason, little girl, to have survived." Bridge wonders, "What is the reason?" At the same time, two other stories intertwine with hers--that of Bridge's classmate Sherm, and an unnamed high-schooler's, told in a second-person narrative. Here Stead discusses how these three tales interlock and diverge, and the question to which she seems always to return.

What inspired you to tell this story about someone who gets a second chance at life?

Something that interests me is this time of life where you're seeing the world outside in a broader way. That also includes seeing yourself from the outside. That's a complicated thought, at an interesting, exciting, fun, scary time of life. It's another way to explore identity.

Who is your true self? Is it the person inside or the person other people know? At this stage, at age 11, 12, 13, 14--depending on who you are--half the time you're seeing yourself from the outside. Maybe from a boy's point of view, also a girl's point of view, your mother's, your friend's. It's the agony of feeling alone in your consciousness: Does anyone really know who you are inside?

A lot is the internal experience versus the external, how you're putting yourself out there and comparing that to what's inside. Liar & Spy was about an attempt to protect yourself--too much, possibly. In this story, they're not protecting themselves; I think Bridge's body knows her fear more than her brain does. She manifests her remaining fear physically more than emotionally or intellectually. But she has a lot of questions. I don't think she's afraid of them. They preoccupy her.

Tell us about the mysterious high-schooler, the one revealed through the second-person narrative, and her bond to Vinny.

Between that character and Vinny, there was a real emotional connection, which was broken. Sometimes at the root of those friendships, there's something real. That's another incredibly painful thing about childhood--and adult--friendship. Sometimes you have to recognize that a friendship is over. The answer is not always to fix it. Sometimes the answer is: the person you had a friendship with is gone, or the person you were in the friendship is gone. I think that's a lot of what that struggle turns out to be in the story.

Many of the complications in the friendships in this book involve triangles, when two team up and the third stands on the outside.

The three main characters, Bridge, Tab and Emily, are three strong girls with a strong friendship. I knew from the beginning--and there are few things that I know at the very beginning-- they'd support each other through the story, and there wouldn't be that kind of torture or pain that can go around when you have a friendship or a trio.

In the high school story, it wasn't going to be that way at all. That's a less detailed view of a situation where things fall apart. There's the relationship between Vinny and Zoe, Vinny's sidekick. The way she's remained Vinny's friend is by becoming a shadow. For the high-schooler, whose story we're learning throughout the book, that's not the way she wants to go. Realizing that brings her a lot of pain. It means she has to leave the relationship. Hopefully both feel familiar. I've had friendships that feel like Bridge's friendships, and then others more like the high schooler–Vinny relationship.

What happened to Bridge has a ripple effect on so many others. That's a theme that Goodbye Stranger shares with When You Reach Me--the idea of one action leading to a chain of other events.

That was something that developed as I wrote the story. I do remember having a more heavy-handed connection between Sherm's story and Bridget's accident in an early draft. I don't like to point too hard or put in too many aha moments. I prefer if my aha moments are emotional beats--something internal. My own responses are strongest when I'm reading about an inner realization or an emotional pivot of some kind.

The New York setting in your novels--When You Reach Me, Liar & Spy, and now Goodbye Stranger--is so real. There's a sense of timelessness to the city, almost like a Woody Allen film. How do you do that?

I think that stuff is mostly subconscious. I do myself the big favor of setting my novels in places where I've spent a lot of time. That's because it's much easier to write a story set in a place where you've internalized the setting already. You don't have to ask yourself about authenticity because you know it on an instinctual level. What I'm trying to do usually is build a story with a lot of tiny little fragments that I spend a lot of time picking up and arranging. I can see everything more clearly against a backdrop I know really well.

How does a new project begin for you? Does an idea hit you like a lightning bolt? Does a character introduce him- or herself to you?

This at the very very very beginning was a book I planned to write about Candy, Safer's sister in my last book [Liar & Spy], three years later. But the person who was being realized on the page was just not Candy. I had to switch gears and discover who the person was I was actually writing about, and what her history was.

I figured out fairly quickly that Bridge was going to be Bridge. I never plan stories; I might have a fragment in my mind or something that happened in my parenting community long ago, or someone else's parenting community. It went very slowly, just writing scenes about the characters and watching them talk to a lot of people. It's the best way to figure out who they are and how they talk. I abandoned the computer and wrote it mostly longhand. It was the best way to keep moving forward.

A lot of writing is tolerating the feeling of not knowing. There's a temptation to go back and reread instead of pushing forward into story. I sat away from my computer and away from the temptations of the Internet and wrote every day until I discovered something I didn't know.

And then there's self-confident Adrienne. Where did she come from?

It's always really fun to have a character who is not struggling at all. It's a nice place to rest as a writer. Adrienne's my person who's not struggling. She's a bit older than all the other young women in the story. She's a nice counterpoint and an interesting character for me.

She's sort of a model of a person who is living the life she wants. That's a big part of the struggle that some of the other characters are having. How do you go about building the life you want so you can live as the person you want to be? Hopefully that includes acting in a moral or decent way toward other people, making choices that respect who you are as a person.

There are times in life where that feels like a real juggling act. I think middle school is often where you're first attempting that in a complex way. Kids today also have these virtual selves that they create--an online self consisting of a collection of friends, a collection of photos, a collection of things you've done that you lay out for people to see. That's also challenging.

You explore different kinds of love--platonic love among friends, self-love and budding romantic love.

I wanted this to be a serious book about love. Not dramatic love, but significant, meaningful love. I was absolutely aware that I was painting a lot of different kinds of love--everything you mentioned plus Bridge and her brother, and Emily and Patrick. There's so much happening at this time of life. There are some who are ready for a little more, and others who are nowhere near any kind of physical relationships. I wanted to show a lot of different ideas.

I get very suspicious when I feel like one character represents a point of view and that character is right about everything, and another is unmitigated evil. That's not really how we encounter people most of the time. So I really tried to show everyone making mistakes. We probably wouldn't agree about what all the mistakes are. If we asked seventh-graders about what mistakes these characters make, I don't think they'd all come up with the same list.

That's the kind of story I try to tell. I was mostly trying to find a lot of pleasure in the way people love each other in this book but also acknowledge the ways we can get hurt.

When you explore a world and bring up a lot of questions, and everyone is making mistakes, that's the kind of book I like to read.  --Jennifer M. Brown
