Full of "can't look away" moments， Dear Killer is a psychological thriller perfect for fans of gritty realistic fiction such as Dan Wells's I Am Not a Serial Killer and Jay Asher's Thirteen Reasons Why， as well as television's Dexter. Rule One—Nothing is right， nothing is wrong. Kit looks like your average seventeen-year-old high school student， but she has a secret—she's London's notorious "Perfect Killer." She chooses who to murder based on letters left in a secret mailbox， and she's good—no， perfect—at what she does. Her moral nihilism—the fact that she doesn't believe in right and wrong—makes being a serial killer a whole lot easier . . . until she breaks her own rules by befriending someone she's supposed to murder， as well as the detective in charge of the Perfect Killer case. As New York Times bestselling author of the Gone series Michael Grant says， Dear Killer is "shocking， mesmerizing， and very smart."
