In “Dead Man Floating,” a sailboat crashes into the fishing pier on Pensacola Beach, Florida, where Sydney Harrell and Gena Sandlin have their chairs and cooler planted in the white, powdery sand. Sydney, a registered nurse, swims against the current and hauls herself aboard and finds an injured man floating face up. While administering first aid, Sydney feels the boat shift and is relieved that help has arrived. Her relief quickly turns to angst when she is joined by her ex-husband—Mark Penrose, FBI agent. A recent divorce fails to extinguish the flames between Sydney and Mark, and their close encounter fans the smoldering embers. When the injured man dies at the hospital where Sydney works, she and Mark find themselves in the middle of a federal investigation and international intrigue.
