"Slimy Underbelly" by Kevin J. Anderson

A witty monster mash detective story featuring the case files of zombie detective Dan Chambeaux. He's your typical average wiseguy except he's dead. Ten years ago something happened to the world and some people woke up a little different than others. Dan woke up in his grave, dusted himself off and got back to the business of helping those in need. Whether it's future super villains or frog demons opening up a new spa for the masses of monsters who could use stress relief, Dan's your man. With his ghost sweetie Sheyenne and human partner Robin as his side kicks, he's got it made. However, when you throw in weather wizards running campaigns for top position and causing weather to change as quickly as one block away not to mention the illicit love child of a senior elder god trying to flood the world with effluence to prove he's worthy of her love, things get a little, messy.
