Starting in St. Louis, Missouri, River Rat journeys down the Mississippi River for an adventure of discovery. The river measures 2,320 miles and can be very wide in places. There are a lot of exciting things to see.

Along the way, River Rat experiences the sights and sounds typically found on a large waterway, from fishing to birds to wildlife and more. He arrives in New Orleans, Louisiana, just in time for Mardi Gras.

Inspired by author Nitha Ann Nebbitt's experiences on the Mississippi as a child, this picture book for children introduces kids to nature and the wonder of this mighty river.
