Atra Hart has spent the last seven years locked away in Vanishing Plains Psychiatric Hospital. In that time, her shadow has transformed into its own entity and is growing stronger by the day, threatening to devour her mind. She calls that shadow Dread, and only her missing father knows what it is.

When a fire breaks out at the asylum, Atra makes her way to freedom just in time to see an electric-purple rift sunder the sky. Like Dread, the rift is only visible to her.

Atra's already loose grip on reality unravels when she learns the rift is a gateway to the world of the dead. And the Queen, an ancient evil lurking on its fringes, wants Dread for her own.

Even worse, Atra can't tell if any of this is really happening. She might have escaped one asylum, but the closer she gets to unearthing answers about Dread, why her father knows it's there, and its role in the Queen's plans, the more she risks getting trapped inside her own mind forever.

Maybe some truths are meant to stay buried.
