Willa Celadon is fine surviving the apocalypse alone. New York isn't the same without the F train and iPhones, but she's got an old camera, a battered pickup truck, and her dog Donut to keep her company.
It's been seven years since the Pulse plunged the world into perpetual darkness. Life has settled into a new normal-as long as she ignores her strange visions and the rumors of something monstrous lurking in the subway.
All that changes when Asher-amateur car mechanic and disgustingly good guy-saves her life. Suddenly she finds herself with a circle of friends, a steady job, and a mysterious boyfriend. For the first time in years, everything is slightly better than fine.
Until the night she finds herself kneeling in Asher's blood.
Wrenched into the Umbra-a magic dimension filled with supernatural beings and even more darkness than her own-Willa races to find the connection between her old secret and new power to save everyone she has reluctantly grown to love.
