City Limits — Sheralyn Pratt

In the third installment of the Rhea Jensen series, Rhea's best friend Kay McCoy moves to Salt Lake City to keep a closer eye on Rhea, and Rhea worries that Kay wants things to go back to the way they were in Los Angeles - clubbing, dancing, and men. But when Rhea agrees to do a simple, harmless favor for Kay, she unwittingly sets off a series of events that ends up with a secret society appearing right at her door. The stakes are higher than ever - solving the case means more than just collecting her weekly paycheck. This time, it's a matter of life and death.
