A madcap collaborative mystery from 13 prominent Floridian writers. Originally serialized in the Miami Herald, the tale follows an 102-year-old environmentalist, a manatee named Booger, a severed head that resembles Castro -- and that's just the beginning. Carl Hiassen, Dave Barry and Edna Buchanan are just a few of the authors who contributed a chapter.  (FLA39, $12.95)
