Whoever goes down to the Bottom never returns. The original town lies abandoned under the megacity. Veiled by perpetual mist, it terrifies the residents of the multilevel megapolis with legends of dreadful creatures spawning in its depths.

As a well-behaved megacity resident, Ellie was content with her safe, windowless apartment and non-demanding job—if only the nightmares could stop. But they kept tormenting her with scenes of brutal murders. Ellie’s life spirals when she sees a face in the news—a face she’s seen die in her dreams.

Now desperate to warn a stranger, she must descend to the Bottom to save him and see for herself if the legends are true.
