A girl detective. A boy genius. A warrior princess. A young magician. Four young people with extraordinary gifts. For years, they solved mysteries, caught crooks, and slayed monsters. They were secret heroes, keeping an idyllic small town in the middle of America safe from the things that lurked in the dark. For twenty years, the four have tried living like normal people. Now their past is coming back to haunt them. The darkness is gathering once more. They're summoned back to their hometown to face it, along with everything else they left behind. Whether they want to or not, they'll have to be heroes again. Last time, they saved the world. This time, they'll have to do something much harder. They'll have to save each other.
