Based on board a Royal Fleet Auxiliary hospital ship, the RFA Apollo, Adams, Lizzie, and the rest of the crew are supporting relief efforts during the hurricane season. But the Apollo has a dark history, its reputation as an unlucky ship known only to a few. One of the few is Sub-Lieutenant Rebecca Lewis, a newly graduated naval officer with a score to settle that goes back generations.
To the west of the Apollo’s location, a slow-moving tropical storm is causing a major headache for forecasters. Unknown to the crew of the Apollo, they’re much closer than they realise when it develops into a full-blown hurricane. As the storm bears down on the tiny islands of the Caribbean, the Apollo’s path to safety has precious little margin for error. But Sub-Lieutenant Lewis has other ideas for the ship and all those on board. Including Adams and Lizzie, who are unwilling participants in Lewis’s plan.
As the wind and the seas rise, so does the tension on board the Apollo. Can the ship make it to safety before the hurricane strikes, or will Adams and Lizzie feel its full force?
