Night Wolf by Suzanne Roslyn

It was his job to help protect the pack until he found the one that would be his undoing.
He found her beaten and left for dead in the woods. His woods, the one where his wolf pack patroled, and his spirit could be free. Trey never planned to shift back into man, not until he found her.
She called herself Jane Doe, claiming to have no memories of her life before coming to Evergreen, but Trey knows she is hiding something. She’s connected to those woods as much as he is connected to her.
Jane can’t risk anyone finding out her true identity, especially the man who claims they are meant to be together. While her heart disagrees, Jane must find her brother and save the members of her clan outside the shifter reservation.
She was his the moment he found her, but there is some else out there hunting for her. While the tracks take Trey on a chase for answers, his heart and his soul war to do what is right. Having to stand up for herself, Jane will risk everything when the truth is revealed. But will it be enough for Trey to hold on to Jane and protect her from the one she thought to escape?
