A gaggle of eighth graders find the coolest clubhouse ever. Fulfilling the fantasies of anyone who's ever constructed a fort in their bedroom or elsewhere, Korman hands his five middle schoolers a fully stocked bomb shelter constructed decades ago in the local woods by an eccentric tycoon and lost until a hurricane exposes the entrance. So, how to keep the hideout secret from interfering grown-ups--and, more particularly, from scary teen psychopath Jaeger Devlin? The challenge is tougher still when everyone in the central cast is saddled with something: C.J. struggles to hide injuries inflicted by the unstable stepdad his likewise abused mother persists in enabling; Jason is both caught in the middle of a vicious divorce and unable to stand up to his controlling girlfriend; Evan is not only abandoned by drug-abusing parents, but sees his big brother going to the bad thanks to Jaeger's influence; Mitchell struggles with OCD--fueled anxieties and superstitions; and so forth. How to keep a story overtaxed with issues and conflicts from turning into a dreary slog? Spoiler alert: Neither the author nor his characters ultimately prove equal to the challenge. With the possible exception of Ricky Molina, one of the multiple narrators, everyone seems to be White. A terrific premise buried beneath problem-novel tropes.
