Book Description
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.

Book Description
Award-winning author Hadley Dyer’s YA debut is smart, snarky, and emotionally gripping, about a rebellious cop’s daughter who falls in love with an older man, loses her best friend, and battles depression, all while trying to survive her last year of high school. Feisty and fearless George Warren (given name: Frances, but no one calls her that) has never let life get too serious. Now that she’s about to be a senior, her plans include partying with her tight-knit group of friends and then getting the heck out of town after graduation. But instead of owning her last year of high school, a fight with her best friend puts her on the outs of their social circle. If that weren’t bad enough, George’s family has been facing hard times since her father, a police sergeant, got injured and might not be able to return to work, which puts George’s college plans in jeopardy. So when George meets Francis, an older guy who shares her name and her affinity for sarcastic banter, she’s thrown. If she lets herself, she’ll fall recklessly, hopelessly in love. But because of Francis’s age, she tells no one—and ends up losing almost everything, including herself. This is a gorgeous, atmospheric, and gut-wrenching novel that readers won’t soon forget.
