Terns of Endearment

Meg Langslow's grandfather has been booked by a cruise line to give lectures on birds and other environmental topics as part of their ship's education/entertainment itinerary, and Grandfather has arranged for a passel of family members to join him.

The passengers' vacation quickly becomes a nightmare when they wake up to find themselves broken down and in need of repairs in the Bermuda Triangle. To keep the stranded passengers calm, Meg's family and friends band together to keep things organized and provide entertainment. Some even take up the cause of nursing an injured tern back to health.

But things get even worse when a crew member announces to all that a woman has jumped overboard, leaving behind her shoes, shawl, and a note. The note reveals she's the mortal enemy of group of writers who came on board for a retreat, and the group is split on whether suicide is in-character for her. Meanwhile, grandfather's assistant Trevor seems to have gone missing too!

The captain decides not to investigate, saying he'll notify American authorities when they reach their destination. But Meg's father thinks they should find out whether there was foul play while the prime suspects are all stuck on board. Who wanted the writer dead? Why doesn't the captain seem concerned? What happened to Trevor? It'll be a race against the clock to solve these mysteries before they make the necessary repairs and return to shore.
