Eleven-year-old brainiac Milton Fauster and his sticky-fingered goth sister, Marlo, face new challenges in the circle of Heck where dead, young overachievers go. Along with drawing the terrifying attentions of pitchfork-wielding demons, a fallen angel assassin, B. F. Skinner, Kali the Destroyer (Heck is an equal opportunity afterlife), and more, the two also find themselves at the center of a plot to transform the world of the living into a rigidly controlled, all-adult society in which joy and joking are criminalized. The pacing lags in spots, but Basye's rare gift for silly wordplay continues to animate an unusually "scarylarious" series.

In this sixth parody of purgatory, Milton and Marlo are sent to Precocia, where intelligent children grow up too fast. As kids train to work boring grown-up jobs, Marlo and Milton discover a plot to end childhood and transform the living world into a joyless, all-adult society. The witty wordplay will continue to delight fans of this mildly dark but not-too-scary series.
