Boat Trip: A totally addictive murder mystery full of twists

Duchess is about to set sail from Scotland to St. Lucia. But before she even leaves port, an argument erupts. It's only the first in a series of unsettling events that will beset Helen, the skipper, her best friend, and the remaining crew.

During a port of call in the Canary Islands, tensions mount further when an unexpected guest joins the crew. Then, a near-fatal allergic reaction raises the pressure level--and finally, during a fierce storm, someone goes overboard . . .

Is this a run of bad luck or is one person at the heart of the turmoil and violence? And if so, can the culprit be identified before they reach the Caribbean?
