Bound by moonlight

the long version

"Detective Charlotte Caissie is suddenly sharing drawer space and making local news with her shape-shifter lover, Max Savoie. He's determined to be accepted by her peers--so how can she ask him to return to his criminal roots to help her solve a complex case? Working undercover with her partner to find the serial killer who's kidnapped a colleague's daughter, Cee Cee is caught between her job and her fiercely possessive lover. And when she calls on Max's preternatural talents to aid his hated enemy, she crosses a line that strains their relationship to its limit. With his secret spreading, Max is forced to protect his family and his clan. The only certainty is his love for his human mate--unless the loyalties that define them divide them forever"--Publisher's description.
