Storm Codes presents the sights and sounds of Great Lakes shipping in the late 1960s through seven-year-old Katy's story of hope and determination. As a fierce ice storm rips through northern Minnesota, Katy and her mother wait restlessly for her father's ship to return to their harbor in Duluth. Storm Codes vividly combines historically based illustrations with nautical terms and descriptions. Katy even creates her own secret code to help bring her father home safely.
