Lou is an offbeat, sexy young woman who just happens to be a Da erwolf, able to transform into any animal she likes--though she prefers to be a panther. Steeped in Da erwolf tradition and adept at living undetected among humans, Lou infiltrates the French secret service in order to track down a rogue Da erwolf who threatens to end the peaceful balance all other Da erwolves strive to maintain. As she tries to restore order in her community, as well as in the whole of Paris, she meets the man she didn't think existed: her perfect mate.

With an inimitable perspective on life, the constant threat of danger looming, and love in the air, Lou demonstrates time and again why humans should be thankful for animal instincts.
