The Sleep Garden explores and pushes the boundaries between fact and imagination, real and surreal, and life and the afterlife.

In an underground apartment building called "the Burrow"—essentially purgatory—"twilight souls" inhabit the space between life and death. Interwoven with their stories are those of inhabitants of the living world: a retired sea captain, a psychotic former child actor (possibly the sea captain's illegitimate son?), and the technicians who monitor the Burrow, making sure its occupants have a constant supply of oxygen and food. Through all of their stories, and the ways in which their lives, past and present, intertwine, Krusoe creates a poignant story about what constitutes a life, what remains when we die, and what we possibly carry with us into the next world.
