A body count is never a good vacation selling point.
In a world of luxury and relaxation, the Ocean Summit stands out during its inaugural cruise, but not for reasons the cruise director would like.
Forced by her agent and publisher to take a much-needed cruise vacation, investigative journalist Claire Mills finds work harder to forget than she anticipated when the cleaning staff discover her neighbor dead on the first day of sailing. The ship's authorities have ruled it a suicide, but Claire suspects murder. With the help of the delightful assistant cruise director Moira, Claire conducts her own investigation.
But the deeper they get, the more clues they collect, and the danger escalates. With the killer on their trail, Claire and Moira must decide what's more important, finding the killer or surviving eight days together at sea.
