Lost Faith by April Zyon

Gabriella Moreno was just a job, in and out to gain the objective, the death of her father. She turned out to be far more than that to Tobias Casey, however, from the moment he laid his hands on her too hot for words body.
Gabriella had just come home from a two-year stint abroad. The first night home she snuck out, never dreaming for even a moment anyone would be stupid enough to take her. Boy, was she wrong.

Faced with brutal truths, Gabbie followed her gut, and her heart, which, it seemed, all led to one place, Tobias. The heat of her homeland was nothing compared to the touch of this man. In his arms, she found something she had craved all her life, the other half of her soul.
Yet, how can she ignore the fact that the man who owns her heart is also the man who wants to take the last of her family?
