From the Newbery Honor-winning author of Three Times Lucky comes a middle grade WWII spy mystery with as much humor and heart as high stakes

Twelve-year-old Stick Lawson lives on Hatteras Island, North Carolina, where life moves steady as the tides, and mysteries abound as long as you look really hard for them. Stick and her friends Rain and Neb are good at looking hard. They call themselves the Dime Novel Kids. And the only thing Stick wants more than a paying case for them to solve is the respect that comes with it. But on Hatteras, the tides are changing. World War II looms, curious newcomers have appeared on the small island, and in the waters off its shores, a wartime menace lurks that will upend Stick's life and those of everyone she loves. The Dimes are about to face more mysteries than they ever could have wished for, and risk more than they ever could have imagined.
