Guarded Heart — Anya Breton

Someone is trying to kill high priest Morgan Seaton, but the last person he wants protecting him is people-hater Brook Calder -- a fellow Water witch from his youth. He values the witches of his coven too much to put them in danger from her shoot-first-ask-questions-later methods. But the head of Neptune's Rangers assures Morgan that Brook is the best of the best, so Morgan has no choice but to accept help from the one witch he's never been able to entice.

If they can stop giving into their scorching desire everywhere -- including the back of a limo or the bathroom floor -- he might survive long enough to find out who wants him dead.
