So B. It

Now a major motion picture starring Alfre Woodard, Jessica Collins, John Heard, Jacinda Barrett, Cloris Leachman, and Talitha Bateman-in theaters October 2017!  From acclaimed author Sarah Weeks comes a touching coming-of-age story about a young girl's cross-country road trip to discover the truth about her parents, which the New York Times called "a remarkable novel." Perfect for fans of Rebecca Stead's When You Reach Me and Ali Benjamin's The Thing About Jellyfish.
She doesn't know when her birthday is or who her father is. In fact, everything about Heidi and her mentally disabled mother's past is a mystery. When a strange word in her mother's vocabulary begins to haunt her, Heidi sets out on a cross-country journey in search of the family secrets of her past. Far away from home, pieces of her puzzling history come together. But it isn't until she learns to accept not knowing that Heidi truly arrives.
Her journey across the country uncovers more than just clues about her past-it reveals the true meaning of home. Found Family: With a loving but mentally disabled mother, Heidi relies on her agoraphobic neighbor, Bernadette, who teaches her everything she knows about the world from inside their apartment. A Heartwarming Mystery: Haunted by a single, mysterious word from her mother's limited vocabulary, Heidi is determined to uncover the secrets of where she came from, no matter how far she has to travel.
Mother-Daughter Story: A deeply touching novel that explores the powerful, unspoken bond between a girl and a mother who loves her fiercely, even if she can't care for her. A Journey of Self-Discovery: Far from home and all she has ever known, Heidi must piece together a puzzling history and learn that sometimes, the most important truths aren't the answers you find, but the peace you make with not knowing.
