FBI Special Agent Cass Cosay is taking time off when he finds himself thrown into a dangerous situation. He sees Dylan Scott, a fellow resident in the Tucson's Casa Pacific apartments, being attacked and threatened with abduction. Cass jumps into action and comes to her rescue. And there's that dog-fighting ring Dylan insists on investigating, and the mysterious criminal who shows up on a regular basis at her accounting firm. Dylan attracts trouble, and Cass is determined to keep her safe. He gets help from apartment manager Logan Reid. This mystery with a love of horses and a touch of romance is a fast and compelling stand-alone story, and #2 in the Iron Horse Mystery series.
