Thirteen is supposed to be fun—birthday parties, friends, and maybe a phone. But when Quinn’s dad returns from overseas, she’s convinced he’s a spy. Suddenly, her ordinary world is anything but.
 
With a big dance competition looming, Quinn recruits her friends to form their own spy squad—each with a code name and a special skill. Together, they must unravel the mystery of a magical music box… before it’s too late.
 
Full of friendship, family, and fearless adventures, this is a story about curiosity, courage, and the kind of bravery that only a thirteen-year-old can pull off.
