I must confess that none of these compels me. But if I were choosing, Passage Crew would be a definite first choice, followed by Hurricane Season with a substantial gap, and after an even bigger one by A Very Distant Mirror. (The strong D&Dish elements are a big factor in this last.)

If you're looking for weird Florida, by any chance have you ever seen any episodes of Nip/Tuck? C and I watch all the Florida seasons. Its two morally challenged plastic surgeons ran into a lot of twisted situations. Other possible sources could be Dexter (the TV series; I looked at the first book and could not read more than a page of it, so I can't recommend it) and John D. MacDonald's Travis McGee novels.
