When her grandmother and cousin are "accidentally" killed in a drone strike in Yemen, Samiya wants answers. She writes emails, pesters her local politician, starts a petition—but no one will help. A less brilliant, less resourceful, or less determined girl might have given up. But Samiya won't let their lives mean nothing. Disillusioned with her friends, her parents, and life in general, she vents her anger in chatrooms, where she makes online allies who willingly loan her their skills. Her alias, Angel, is born, as is a completely audacious plan which no one will be able to ignore.
