Suckerville by Chris Sorensen

A Creature Feature with Teeth
JD Speers is having a stretch of bad luck: his wife left him, the law is on his tail, and to top it all off, bloodsucking leech people are attacking his favorite bar. Together with his buddy Rowdy and the barflies of Doc’s Dockside Tavern, JD must stop the suckers before they spread their contagion up and down the Mississippi River.
