Once upon a time a creek burbled up and tumbled across a prairie valley. It was filled with insects and brook trout that ate them, frogs that chirruped and birds watching for bugs and fish. This is a true story about a man named Mike who went looking for that creek long after it was buried under fields of corn. It is the story of how a creek can be brought back to life, and with it a whole world of nature. This heartening tale of an ecosystem restored in the Driftless Area of northeast Iowa unfolds in a way that will charm and inform young readers who are drawn to a good mystery, the wonders of nature - and, of course, big earth-moving machines.
