Five Feet Apart meets Tell Me Three Things in this YA contemporary novel about two sisters, one summer, and a diagnosis that changes everything. Abby needs to escape a life that she no longer recognizes as her own. Her old life--the one where she was a high school volleyball star with a textbook-perfect future--has been ripped away. Abby and her sister, Brooke, have received a letter from their estranged dad informing them he has Huntington's disease, a fatal, degenerative disorder that you wouldn't wish on your worst enemy. And when the sisters agree to genetic testing, one of them tests positive. Fleeing to Catalina Island for the summer, Abby is relieved to be in a place where no one knows her tragic history. But when she meets aspiring documentary filmmaker Ben--tall, outdoorsy, easygoing, with eyes that don't miss a thing--she's thrown off her game. Ben's the kind of guy who loves to figure out people's stories. What if he learns hers?
