Legendary illustrator Arthur Geisert returns with the final installment in his Clayton County trilogy—this time imagining how the Turkey River trolls and townspeople must come together to save their shared home from flooding. The trolls of the Turkey River live underground in hollows they call homes.They are fun loving and communal, but also mischief-makers who sometimes go too far!From sowing corn that sprouts up through the cracks in the pavement to making Main Street as slippery as an ice-skating rink, there’s nothing more fun for a troll than pranking the townspeople.But when the waters of the Turkey River start to rise and threaten to flood, the trolls rush to warn the townspeople.If there’s any hope of averting disaster and saving the place they both call home, the trolls and townspeople must put aside their differences and work together!
