Nikolai Silvetti stopped using his real name a long time ago. After a decade of sanctioned kills, he's known only as Sinn-a ghost in the underworld, a weapon forged from trauma and blood. He doesn't believe in softness. Not until he sees her... Seraphina Payne works for his cousin-the Don of Italy-and Sinn mistakes her for someone else's wife, someone else's responsibility. But when the truth shatters his assumptions, obsession takes hold. She isn't married. She's surviving. And Sinn decides survival isn't enough-he wants her to live, belong, and break beneath him. He doesn't care what he has to destroy to have her. She's not his. But he's going to ruin her anyway. "I found salvation in the most dangerous man alive. Because heaven isn't light-it's kneeling in the dark, worshipping the devil who tastes like sin, and letting him burn every trace of innocence from your soul." Previously known as 'The Enforcer'.

Dahlia has lived in our universe as an immortal for centuries. She has a soft spot for this universe - all the good and all the bad - and has made the best of an admittedly bad situation. Her universe? It...went through some things, but who cares, when ours is so inviting? The thing about peace and tranquility is that it's always fleeting, and when her former best friend is murdered in cold blood, Dahlia will put her own life - and that of a very unwilling, broody sidekick - at risk to solve a murder that should never have been possible in the first place.
