Meg Langslow is only too pleased to join her grandfather on a cruise ship vacation dedicated to lectures on birds and other environmental topics. But Meg's vacation quickly becomes a nightmare when the ship breaks down and needs repairs... in the Bermuda Triangle. Ahoy! If that, plus nursing an injured tern back to health, isn't enough, a woman has jumped ship - leaving behind a note that reveals alarming details about her fellow writing-retreat members who are still onboard - and Meg's grandfather's assistant, Trevor, is now missing too. Suspicions are flying all around... Soon it's up to Meg to swab the decks and solve this killer case before more bodies are swept to shore.
