Big Bad Wolf - Night Fall Series, #13

Ginnie Martin is a badass. She was born that way one horror-filled night. Forged in blood-her own and her family's. All were ravaged by savage beasts. Her vampire savior recruited her to fight with his small army against the creatures responsible for her devastating loss. But now, he's asking too damn much. He wants her to open her home to new allies who, until only recently, were their fiercest foes.
Wolves. Calum Fletcher already bristles against providing muscle to a vampire force. Content living in his remote mountain cabin, he's never been much for mixing with other wolves, much less making nice with vampires. He was already having a hard time dealing, but the woman letting him bunk in her home wears an even larger chip on her shoulder. Quickly, his new favorite sport is goading her into losing her temper-because everyone knows a vampire's bloodlust leads to very sexy places.
