When Henry is badly hurt defending a friend and her ward, Jackson and Ellery will do everything they can to track down his assailant. The trail leads to a puzzle much more complex than a random shooting. Somebody in their city is preying on teenagers in a most insidious way, and nobody in their circle is going to let this stand. Does Jackson finally have emotional defenses to fight his own demons while he's slaying dragons for the family he's found, or will he drown in his own remorse?
