Wolf in his Heart by N.J. Walters

He’s a wolf where it counts—in his heart and in her bed.

Exiled from her wolf pack for rejecting her parents’ choice for a mate, Rina Matheson has been on her own for over a year. Now she’s running for her life from a man who knows what she is and is obsessed with hunting her down.
Sage Gallagher—organic farmer, half-breed werewolf, and member of the Salvation Pack—finds more than a lost hiker while camping in the Great Smoky Mountains. So much more. Instant attraction slams through him with knee-buckling power the minute he sees Rina. His first instinct is to get her home where he and his pack can protect her.
Rina doesn’t trust easily. Especially not half-breeds, who she was raised to consider abominations. But Sage’s quiet strength calls to her lonely soul, and amazingly enough, her wolf responds. As he slowly works his way past her guard, she is soon in danger of losing her heart—even as danger draws closer to taking her life.

Warning: Your heart is in danger of being lost to one very special half-breed werewolf.
