Bücher der Reihe Lessons in Peril

On a school camping trip, fifth graders experiment with a dangerous new hallucinogen and die in a horrific accident, their deaths shattering the quiet town. Assistant Superintendent Ken Parks, hoping to redeem a fatal mistake from his past, grasps the opportunity to conduct the district investigation of how students are getting the drugs. Almost before he begins, the cops make a stunning arrest. But Parks battles on, convinced the real pusher is still out there, poisoning more kids until he receives an anonymous threat: if he continues, those close to him will pay. Is Parks willing to risk those he loves for a chance at redemption?
