Guardian Daire has one mission: eradicate the lycanthrope before they can prey on the citizens of St. Joseph, Michigan. Then, he meets the stunning Grace. He's an immortal dragon shifter tied to the goddess Astraea and bound to the constellation Aquarius. He can never have anything more than a passing relationship, but that doesn't stop him from craving her. The full moon is quickly approaching, and if he fails his mission, Grace and all the residents of the tiny town will become victims of the lycanthrope.

Single mom Grace is barely getting by, living paycheck to paycheck. Luck isn't on her side, and things only seem to be getting worse. Little does she know, her whole world's about to get turned upside down. Grace is thrust into a world she never knew existed. Determined to work with Daire to save her town, she offers to help the Zodiac guardian. He's immortal, and she's human. But that doesn't stop her from craving his touch.
