Best of BookTok: Caught between four dangerous men, one woman indulges her hidden desires, in this deliciously dark reverse-harem romance.

The Vipers run this town and everyone in it. They make deals as sordid as their business–and they have no mercy. They’re a mafia family only an idiot would mess with, so of course my estranged, abusive father did just that. Then he sold me off to them to cover his debts.

Now, trapped in their penthouse, they say I’m their toy to play with and discard whenever they see fit. But the Vipers have no idea who they’re dealing with. I intend to take advantage of the hunger in their eyes.

As their scarred, blood-stained hands roam my body, I’m getting under their skin, turning their desires into an addiction they won’t be able to shake. What’s more? I’m indulging my own dark fantasies, ones I’ve never been able to satisfy. . . until now.

Ryder, Garrett, Kenzo, and Diesel think they’re in control. They think that I’m their prey. But this girl? She has fangs too.

This deluxe edition features sprayed edges with stenciled artwork, a signed letter from the author, and five bonus scenes.
