Down Will Come Tiger. Tiger Shifters, #6

He'll stop at nothing to get revenge.until he meets her. Ten years ago, tiger shifter Joseph Bennett lost everything to a human serial killer. His only thoughts now are of revenge and death, his emotions shut down so he can stalk his prey. Then she appears in the dead of night and changes everything. Joseph hates the changes, hates the returning feelings, and most of all, he hates the woman who started it-even as he can't stay away from her.
She cracks him open, and after all these years, he has no idea what monster will emerge from his black soul. He only knows that keeping her safe matters. Socialite Paige Williams has remained silent about her brother's crimes for years. When she meets Joseph, she knows she can't keep her secrets any longer. But going after her brother comes with huge risks, because if he catches her, she's dead. Her only hope is the emotionless tiger shifter whose presence sooths her battered soul and helps her find her inner strength.
She never expects to fall in love with him. As a killer stalks them, passion ignites a fire between them, fierce and hot. And when the flames part, they'll either emerge whole.or dead.
