Skinny Dip by Carl Hiaasen

Joey Perrone is a woman with a mission. She's just been pushed overboard from a cruise liner by Chaz, her scumbag husband, and survived to tell the tale. But rather than reporting him to the police, she decides to stay dead and - with a little help from her friends and a few of Chaz's enemies - instead of getting mad, she's going to get even. Filled with a host of endearingly offbeat characters, and a narrative that is hilarious, romantic and thought-provoking by turns, "Skinny Dip" takes us on a journey through the warped politics of Southern Florida and through the madness created by the human heart.
