City Attorney Regan Desanto moved to town a year ago after her partner of twenty years dumped her for another woman. All she wants is to be near her ailing grandmother and to work ordinary, boring municipal cases until she can get her life back together. Beat officer Sydney Cabot is a chronic serial polyamorist who craves the adrenaline rush on and off the job. She has never wanted to be or tried to be faithful to one woman. When Syd is slapped with a wrongful death suit, Regan, the most uptight, controlling, and monogamous woman Syd has ever met, is assigned the case.

Sydney doesn't trust Regan, and the feeling is mutual, but they have to work together—and what's even more of a challenge, they have to figure out how to defuse their growing attraction.
