Book 5: A Stone’s Throw

Flames from Fish Boil OverboilTo most people, Wisconsin’s Door County doesn’t go beyond the peninsula. Did you know, though, that the Door in Door County comes from the narrow water passage called Death’s Door? Grandpa Mike explains how the open waters of Lake Michigan to the east and Green Bay to the west crash into each other here. Stormy weather makes this stretch of water particularly dangerous. Seven-year-old Mallory searches in vain for a floating door in the water as the ferry makes its way to Washington Island. His twin sister Melody is more interested in islands.
