Dagger’s Edge by Lora Leigh

Ivan Resnova wants nothing more than to escape his hard, brutal past. Starting over is not so easy once you’ve been a powerful crime boss but now, instead of being punished for his alleged crimes, Ivan fears that the one woman he can’t forget is in danger of paying the price.

Crimsyn “Syn” Delaney thought the danger she’d faced was over, and that she could resume her life. She never imagined it would return with a vengeance and throw her back into Ivan’s world. But when an attempt is made on her life, she needs Ivan more than ever to keep her safe–even if she is in danger of falling deeply and dangerously in love. . .
