"Everglades" by Randy Wayne White is one in his series about biologist Doc Ford in southwestern Florida. This adventure is located within the Everglades, and includes alligators, swamps, and Native American Indians. The "bad guys" include religious cult gurus, hit men, and land developers. Many of Doc Ford's friends from previous books make appearances, and several new characters are introduced. It's a fun read, and Doc Ford never disappoints his friends.
Love the whole series! You might also like Carl Hiaasen's books. --
