"When a space-based drone conveying part of an orbital defense system plummets into the Caribbean, the U.S. military scrambles to retrieve their missing tech. The nearest vessel to the crash site is Ryan Weller’s personal catamaran, and the top brass waste no time in enlisting Ryan’s help in diving for the drone.
Determined as ever, Ryan locates the missing UAV, but before he and his colleagues at Dark Water Research can raise it from the ocean floor, they come under fire from a detachment of Chinese Special Forces intent on securing the satellite for their own use."
