In this thrilling sequel and conclusion to the City of Nightmares duology, which has been praised as "so much fun readers will stay up all night to finish it" (Kirkus, starred review), Ness is forced to make a twisted deal with the Nightmare Phantom—only to find herself embroiled in the explosive fallout of the agreement when a botched assassination attempt unleashes chaos into the City of Newham.

Nineteen-year-old Ness used to have a vehement terror of Nightmares—people who’d been turned into their worst fears while they slept. Through two assassination attempts, an explosion, and a faustian bargain with a dream demon, she’s finally working through those fears.
