Ally Carter writes books about spies, thieves, and diplomats. She is the New York Times best-selling author of three YA series about the world's best teenage art thieves (Heist Society), the world's coolest spy school (Gallagher Girls, including I'd Tell You I Love You But Then I'd Have To Kill You), and the granddaughter of a diplomat who has to find her mother's killer on Embassy Row. Not If I Save You First is her latest New York Times bestseller. Winterborne Home for Vengeance and Valor is her middle grade debut. Her novels have sold over three million copies and have been published in more than twenty countries. She lives in Oklahoma, where her life is either very ordinary or the best deep-cover legend ever. She'd tell you more, but…well…you know… Visit her at AllyCarter.com, on Twitter @OfficiallyAlly, and on Instagram, Facebook, and Tumblr at @theallycarter.
