Dead Fast — A.J. Stewart

To most people Jamaica is sun, sea and rum drinks by the pool. But Miami Jones and Danielle Castle don't vacation like most people. After witnessing an assault on a young man in Montego Bay, Miami and Danielle are hired to protect a young athlete with Olympic dreams. But there are lots of athletes with those dreams, and not all of them play by the rules. Miami and Danielle find themselves up against corrupt officials, athlete managers with a kit-bag full of dirty tricks, and a local police force that might be in it up to their necks. In a paradise where running fast is the national pastime, Miami and Danielle must go at full throttle to protect their client and help him hit the finish line alive.
