No one really knows what they are. Only that they're the first civilization. Aeons, they call themselves. They're immortal. Powerful. Secretive. And they'll come for her. 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. There’s a heavy price for the safety the Ancients offer, but Wynter will have to pay it. She can't take on the Aeons alone. And she has no intention of dying—been there, done that. Not that she'll be the easy prey the Aeons are expecting. They have no knowledge of the ... thing that lives inside her. You see, when witches are brought back from the afterlife, they don't always come back the same. And they don't always come back alone.

The Ancients and the Aeons. Two groups of powerful immortals that have not seen eye to eye for millennia. And right now, at the heart of their conflict, stands Wynter Dellavale. Wynter is a witch who sought safe haven for herself and her coven in Devil's Cradle. Founded by seven Ancient beings, the Home of Monsters provides protection, shelter, and will never give you up to outsiders . . . providing you pay the Ancients' substantial fee. Wynter already wears the brand of Cain - the mark that she is in his service and that her soul partly belongs to him. But as their relationship deepens, Wynter has to make a choice from which there's no turning back. Cain cannot reveal the nightmare which lives inside him, the beast that could tear apart the woman who means more to him than he ever thought possible. But with his brother Abel out for revenge, and the suspicious reappearance of his parents Adam and Eve, Cain sees that Devil's Cradle is on the verge of war. As the stakes are raised, Cain knows he needs more than anything to keep Wynter safe and by his side - forever.

The Ancients and the Aeons. Two groups of powerful immortals on the brink of destruction, and at the heart of it all stands Wynter Dellavale. Wynter is a witch who once sought sanctuary for herself and her coven in Devil's Cradle. Better known as 'the Home of Monsters', it was a place for outcasts and fugitives. She now wears the brand of Cain, the infamous Ancient, who has claimed her soul for all of eternity and doesn't plan on ever letting go. Together, Wynter and Cain have prevailed over many powerful enemies, but now they face their final - and most terrifying - battle. As the last Aeon left standing, the all-powerful Adam is out for revenge. His terms: Cain and Wynter in exchange for peace. If Devil's Cradle won't deliver them, the full force of Adam's devastating rage will fall upon them all. As the stakes are raised, Cain and Wynter will do whatever it takes to defeat Adam and keep each other safe, even if it means unleashing the monsters that live within them . . .
