Carlie Walker attended the University of North Carolina at Chapel Hill, where she first majored in Peace, War and Defense, a feeder program for intelligence services--before realizing that she is way too anxious to be a spy. Having gone on to study at Oxford University and at City, University of London, she worked briefly in publishing before becoming the bestselling author of seven books for children and young adults. She has a registered 250-pound dead lift, volunteers in a cat shelter, and used to spend her Saturdays practicing Krav Maga. She lives in Atlanta, Georgia, with her husband and their American dingo.
