This time Cruz and family are off to the exclusive, secluded, French-Caribbean Jules Verne's island for a long-overdue holiday. Luck has smiled upon the Cruz family--Cruz, his wife, Dot, and the two kids, Cruz Jr. and Kat. A free vacation during the very weeks the island is shut down for an annual writers' retreat for the top sci-fi authors of Earth! There'll be no vacation for our famous private eye. There's been a murder. So it's Cozy Mystery time, Liquid Cool style! It was supposed to be a nice, quiet, relaxing family vacation. But instead, there's plenty of action, surprises, thrills, and laughs.
