Seventeen-year-old Signal Deere has raised eyebrows for years as an unhappy Goth misfit from the trailer park. When she's convicted of her best friend Rose's brutal murder, she signs on for a secret program and is whisked off to an abandoned sleep-away camp, where she and seven bunkmates will train as assassins. Yet even in the Teen Killers Club, Signal doesn't fit in. She's squeamish around blood. She's kind and empathetic. Maybe that's because Signal's not really a killer. She was framed. And now she's determined to find Rose's real killer and clear her name.
