Bluewater Betrayal — C.L.R. Dougherty

When an old boyfriend cons Liz Chirac into helping him start an all-inclusive charter business, she takes a break from her own luxury charter boat to give their romance another try. She's acting against her better judgment, but Robert Delorme is a past master at manipulating Liz. Her business partner, Dani Berger, and their friend and long-term charter guest, Connie Barrera, are expecting to pick up the pieces when Delorme breaks Liz's heart once again. Liz is dismayed to discover just how ‘all-inclusive' Delorme's charter business is intended to be, and she and her friends are drawn into a web of murderous intrigue in the islands as they sail through the Caribbean to escape the wrath of Delorme's drug-smuggling investors. Bluewater Betrayal is the fifth book of the popular Bluewater Thrillers series.
