A brand-new Southern Gothic horror from New York Times bestselling author of How to Sell a Haunted House and The Final Girl Support Group.

'I did an evil thing to be put in here, and I’m going to have to do an evil thing to get out.'

Florida, 1970.

Fifteen-year-old Neva is taken to Wellwood House, a home for unwed mothers, to see out the final three months of her pregnancy. Her father turns tail without even a goodbye, leaving Neva to endure the isolated maternity home for one sweltering summer with the bugs, the boredom, the awful food, the shunned unwed girls just like her. There, she meets Rose, the righteous hippie; Holly, a fourteen-year-old who refuses to talk, and Zinnia, the cultured sceptic.

Miles from the nearest town and forced to abide by the home’s draconian rules, the girls are powerless, kept in the dark of what is to come. Only that their best option is to surrender their babies and move on as if this never happened

Then one day a travelling library arrives outside Wellwood House. And the librarian presses a book onto Neva, one that promises answers, power, even revenge. A book of witchcraft. But the book demands a sacrifice to work properly. A debt that must be paid. And, if she’s making deals with the devil, Neva must decide what price she is willing to pay.
