Sleeping with Demons

by Lorna Tedder

a Stand-alone in The Secret Lives of Librarians Universe

High‑Concept Tagline: Think The Butterfly Effect meets The Magicians meets The Leftovers – a desperate priest races against time to rewrite history and save humanity by fixing the mind of a demon-possessed empath.

Description: Raven, the prophesied Last Priest of a dying order, faces humanity’s extinction in a post-apocalyptic world shattered by natural disasters. To fulfill the prophecy and ascend to godhood, he needs an empath and an angel—but the only surviving empath, Lilah, is a demon-possessed madwoman, and angels are nowhere to be found in this timeline.

Using The Book of Time, Raven travels into the past to rewrite traumatic memories and heal Lilah’s fractured mind. But each intervention creates dangerous alternate timelines, and he has only one night to free her from demonic possession, find the missing angel, and choose between saving those he loves or preventing the collapse of all realities.
