Beer and polka music reign supreme at Octoberfest, Battle Lake's premier fall festival. To kick off the celebrations, the town hosts a public debate between the two congressional candidates: straight-laced Arnold Swydecker, and slippery incumbent, Sarah Glokkmann. As a reporter for the Battle Lake Recall, Mira James is roped into writing up the word war. But the festive mood sours when a well-known Glokkmann-bashing blogger is found dead ... and the congresswoman herself meets a gruesome fate. To keep the heat off her best friend's fiancé -- an ex-con reporter -- Mira wades through the candidates' dirty laundry, their unsavory secrets, and some murderous mudslinging to expose the killer.
