WHAT HAPPENS WHEN SOMEONE WHO'S ONLY EVER WANTED TO BE A HERO BECOMES A SUSPECT?

When a woman's body is found in a vacant lot, suspicion falls on an awkward teen who lives only a few blocks away, owns several knives, loves first-person shooter video games, and doodles violent scenes in his school note-books. Nick Walker goes from being a member of a Search and Rescue team to the prime suspect in a murder, his very interest in SAR seen as proof of his fascination with violence. How is this even possible? And can his friends Alexis and Ruby find a way to clear Nick's name before it's too late?
