Highland Guardian (Daughters of the Glen, Bk. 2)

Ian McCullough is neck-deep in his own trouble. A half-mortal descendant of Faeries, he's been a Guardian for more than six hundred years, but he's never encountered a woman like Sarah. Assigned to protect her, he finds the job tougher than he could have imagined. Oh, he can handle the stalker, and even the renegade Faeries trying to kidnap her. But falling in love means forsaking his role as Guardian -- which is some-thing he could never do.

But there is no denying the passion that exists between two souls fated to be together.
