Check Mate (Wolf Sisters)

Pilar Rhonda Alvarez lives what she considers to be a neat and calm existence. She's the youngest of three half sisters and a DEA officer with the Miami Police Department, and she and her sisters run a secret PI agency, helping battered and abused women. What's more, she's a werewolf.

Events take a sudden twist, when Alton Succo crashes into her life. Hailing from Sedona, Arizona, he's in town investigating a drug trafficking ring. But Pi's wolf instantly identifies him as her mate. Meanwhile, a case with the agency brings her face-to-face with an old crush. Between old love and new attraction, she's unprepared to face her feelings for the stranger wolf--or his for her. Only time will tell whether she'll be able to keep her head on straight long enough to track down a missing man and find a love that will last.

In this novel, a werewolf working in law enforcement finds herself torn between a crush from her younger days and a strange wolf her heart declares is her mate.
