Can a lost girl save a found dog? Find out in this unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness. Hadley is angry about a lot of things: Her mom going to jail. Having to move to another state to live with her older sister, Beth, even though they haven't spoken in five years. Leaving her friends and her school behind. And going blind. But then Hadley meets Lila. Lila is an abandoned dog who spends her days just quietly lying around at the local dog rescue where Beth works. She doesn't listen to directions or play with the other dogs or show any interest in people. So when Lila comes and sits by Hadley (which is hardly anything, but it's more than she's done with others), Beth thinks maybe Hadley can help Lila. She tells Hadley they'll bring Lila home as a foster dog and Hadley can teach her to follow commands, walk on a leash, and be more of a people dog so she's ready to be adopted. Only working with Lila is harder than Hadley thought, and so is the mobility training she starts taking to help with her failing vision. It feels like Lila is too stubborn to train and that learning to use a cane is impossible. But unless Hadley can help Lila, she'll never be adopted into a home. If Hadley could just let go of her anger, she might be able to save Lila ... and herself. New York Times bestselling author Kody Keplinger weaves an unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness.

In this New York Times Notable Book from one of today’s most acclaimed writers, two lives stretched between two cities converge in a chance meeting that will irrevocably change their lives. “Hadley is a supremely perceptive writer of formidable skill and intelligence, someone who goes well beyond surfaces.”—New York Times Book Review Unsettled by the recent death of his mother, Paul sets out in search of Pia, his daughter from his first marriage, who has disappeared into the labyrinth of London. Discovering her pregnant and living illegally in a run-down council flat with a pair of Polish siblings, Paul is entranced by Pia’s excitement at living on the edge. Abandoning his second wife and their children in Wales, he joins her to begin a new life in the heart of London. Cora, meanwhile, is running in the opposite direction, back to Cardiff, to the house she has inherited from her parents. She is escaping her marriage, and the constrictions and disappointments of her life in London. But there is a deeper reason why she cannot stay with her decent Civil Service husband; the aftershocks of which she hasn’t fully come to terms with herself. Connecting both stories is the London train, and a chance meeting that will have immediate and far-reaching consequences for both Paul and Cora.
