Moon Caught - Conney C. M.

Mark meets Kelly while hunting a feral wolf. As soon as he scents her, he's knows she's meant to be his mate. The problem— she's only fifteen and he's over a hundred. Now he has to wait for her to grow up and make her fall in love with him—  and that's harder to do than it sounds when she knows he's the one who decides whether she gets to live or die.
