Secrets in the Moon - The Werewolves of Crescent City, #1

Savage appetites and opulent vices are a way of life in Crescent City, a metropolis split among werewolves and humans. As one of its most beautiful socialites, Cora Marshall thrives on scandals and the attention they bring. Yet even she is stunned by her father's murder... and by becoming the prime suspect for it. Determined to prove her innocence, Cora hires Detective Sam Hayes, an irresistibly handsome werewolf with as many secrets to his name as she has to hers.
To uncover the truth, they must trust each other with everything--especially now that the real killer hunts them throughout the city.
