Wolf Mate Surprise by Caroline S. Hilliard

There is no second chance at love. Or so he thought.

Julianne is instantly attracted to the gorgeous man at the pub. But he is gone before she can pluck up her courage to talk to him. She has all but given up hope of ever seeing him again when he comes to her rescue.
Being cornered by her possessive ex leads to the revelation of a world she never knew existed. One where shifters and witches are real and living among the unsuspecting humans. And the amazing man she’s falling for is one of them. But would he have told her if he didn’t have to?
Duncan can’t forget the wild-haired beauty from the pub. If he didn’t know better, he might have thought that she’s his true mate. But she can’t be. He already met his mate years ago, and she refused him.
Somehow Julianne dulls the pain of his mate’s rejection, and he’s pulled to her like a bee to a succulent flower. Even knowing that she can never replace his true mate, and that their fling might be short-lived, he cannot resist her. But can he live with the knowledge that she can never truly be his? And is it fair to her?
