Part of a small demon lair in Las Vegas, tattooist Harper Wallis lives a pretty simple life. That changes overnight when she discovers that her psychic mate, or "anchor", is a guy who's rumored to be the most powerful demon in existence. Compelling, full of secrets, and armed with raw sexuality, Knox Thorne is determined to claim her as his anchor, creating a psychic bond that will prevent their inner demons from ever turning rogue. The billionaire also wants Harper in his bed.

Witch Wynter Dellavale knows that for certain. Because in unfairly trying to execute her, they started a chain of events they're struggling to stop. Needing safety, she flees to Devil's Cradle, the home of monsters. A place for the outcasts, the fugitives, the crazies. A place ruled by the Ancients, seven beings who were once banished by the Aeons. Among the Ancients is the infamous Cain, brother of Abel and embodiment of jealousy - who, on another note, wants her in his bed.

Cat shifter Bree Dwyer doesn't fear much. Ironically, what she fears most is the person who was put on the Earth just for her. Your true mate wasn't supposed to be cruel and twisted; wasn't supposed to be someone who'd never love or want to claim you. The rumors that her true mate is dead bring her only relief. Bree's intent on moving forward with her life and building a future with someone else. Sadly, the male she wants most is one she can never have - a hot-as-sin wolverine shifter who happens to be her boss...and the cousin of her predestined mate.

One heroic act damned me for eternity. With a name like Tor, I should have been a hero, just like my father and twin. Turns out I’m not. Not even close. Instead I’m the very thing we hunted. A depraved monster. I thought there was no escaping the curse. No hope for a future. And then I met my mate in the unlikeliest of places: Blackwood Asylum. A place for criminals. Power-hungry madmen. Supernatural outcasts. And her, the curvaceous writer who sees ghosts.

Mercy Thompson's life is not exactly normal. Her next-door neighbor is a werewolf. Her former boss is a gremlin. And she's fixing a VW bus for a vampire. But then, Mercy isn't exactly normal herself.
