Shadow Bound by Kayleigh King

Ransom Weylyn is a hunter. Hidden behind his easy smile and laid back attitude is a wolf that craves bloodshed and carnage. No one knows how hard he works to keep that part of himself at bay. Not even his family sees behind his calm façade.
But she does.
Isabeau Claremont is a killer. Born and bred to be a weapon and nothing more, she’s embraced the monster they’ve made her. She knows nothing but death and the darkness of shadows. She thought she’d accepted her fate and her purpose, but then she meets him.
And everything changes.
With a connection that runs vein deep, Isabeau and Ransom must find a way to work together without killing each other in the process. A wolf shifter with temperament issues and a vampire with a knack for knives, what could go wrong?
