After Carolina retires from the university, she settles into her perfect life at the Villas with a multitude of activities, seven days a week. When she tires of bridge and bingo, she always has a new Mrs. Craycraft Super Agent book to read. But soon Carolina feels something is missing in her perfect life – adventure, excitement, and romance. She believes a Caribbean cruise onboard the Emerald Dream will provide that.

Once onboard the ship, Carolina and her two friends cross paths with a stowaway, a hunky spy, a smuggling ring, assassins, and kidnappers. As their fears are brushed aside by authorities, the women do not know who they can trust. Everyone – from Mr. Hunky Spy to Mr. Boring Officer – is suspect. In every island port, they search for evidence to prove they’re not batty old women, while trying not to meet an untimely end in the process.
