In the backcountry of the Florida Keys, you can see and hear trouble coming for miles in any direction. That is, if you're paying attention.

Jesse McDermitt lives in the backcountry and very little happens near him that he's not fully aware of. During a quiet moment, he watches a slow-moving shrimp trawler as it serenely cruises by, barely visible on the horizon at the edge of the three-mile limit.

The tranquility of the moment is shattered when the trawler is suddenly demolished in an enormous explosion. What caused the explosion? And why was a woman from Jesse's past on board?

To find the answers to these questions and more, Jesse and friends will work from Miami to Key West, then across the water to Fort Myers. When the bad guys hit too close to home, Jesse retaliates. Furiously.
