On his sixteenth birthday, Francisco "Cisco" Aguilar first sets eyes on Maximilian De Ferrari, owner of Wicked Grounds, an exclusive BDSM club. Cisco has been lost, unsure of what is missing in his life. Over a century old, Max leads a vampire clan, and Cisco is drawn to him in a way he can't explain. The moment he sees Max he knows his quest isn't about what he's been missing, but who.


Five years' wait seems more than Cisco can bear, but he perseveres and on his twenty-first birthday he walks into Wicked Ground. He's unafraid to meet the vampire he's sure is his destiny. Max has been waiting for him, too.


What Max has known all these years, and what Cisco soon discovers, is that more than fate is drawing them together. Iunctio Copula is a powerful binding link capable of restoring cold, dead hearts. With Max and Cisco bound, Cisco will be Max's greatest weakness. Unable to let Max go, Cisco is thrust into a dark world, where he's nearly powerless, left to fight for his life and his future with Max. Worse, he's at the mercy of those who will use him-and hurt him-just to get to the powerful vampire.
