A reluctant teenage killer, the alluring demon she’s bound to, and the headstrong boy she’s sworn to kill are tangled in a web of dangerous desire and sinister secrets in this dark psychological thriller from the New York Times-bestselling author of Boys with Sharp Teeth.

One heart for another. One life for another. And only her soul to pay.

Two years ago, Tara Corbane made a deal with a demon. Each lunar eclipse, she must feed him a lover’s heart torn out by her bare hands—and in exchange, he keeps her sister’s dying heart alive. A desperate deal that Tara fears is making her more and more like Thorn, the twisted but tantalizing demon she's sworn to hate.

Thirty days before the next eclipse, Tara heads to New Orleans, where her newest target awaits. But Rian Connach, the handsome heir to a real estate empire, is nothing like the others. He's single, for starters, and isn't out for love but vengeance. He's hot on the trail of the serial killer he blames for his girlfriend’s gruesome death—a trail that will lead directly to Tara.

As the eclipse draws near, Tara finds herself trapped in a game of cat and mouse. To save her own skin, she must win the trust and ruin the mind of the beguiling and broken boy hunting her, all the while fighting her feelings for the demon whose secrets threaten everything she's ever believed about him, and herself. With Rian getting closer and closer to the truth, and Thorn warning of vicious consequences if she doesn’t fulfill their bargain, time is running out to answer the ultimate question: Is Tara the predator, or the prey?
