Maggie Silver has never minded her unusual life. Cracking safes for the world's premier spy organization and traveling the world with her insanely cool parents definitely beats high school and the accompanying cliques, bad lunches, and frustratingly simple locker combinations. But when Maggie and her parents are sent to New York City for her first solo assignment, her world is transformed.
