“In a Dark Mirror combines true crime and urban legend into something entirely, achingly human. It’s a testament to Kat Davis’s remarkable storytelling that she brings out new facets of the lonely girls who seek refuge in the supernatural, but perhaps her most powerful feat is in following those girls into adulthood, examining the grown women forced to grapple with the real-life consequences. Bold, haunting, and incredibly difficult to put down, this astonishingly confident debut will have you looking into every face you encounter and wondering about the secret darkness we all hold within.”—Sara Flannery Murphy, author of The Wonder State

Once you start reading this book, you won’t be able to stop!”—Jennifer Close, author of Girls in White Dresses

“Get your nightlight ready—In a Dark Mirror is the kind of book you stay up all night to read, and then you’ll spend the rest of the week thinking about it.

Kat Davis is a star.”—Annie Hartnett, author of Unlikely Animals
