What if everyone's favourite band was working for the bad guys? Only Frankie can save the day!

Junior Griffin agent Frankie Fox is undercover on her second mission, visiting an international kids' robotics competition in Scotland. She's investigating the evil Alliance's robot army when she discovers something even more terrifying: the world's number one boy band, Band of Brothers, is brainwashing kids to serve the Alliance!

To crack this case, Frankie will need to solve puzzles, deprogram evil robots, and sneak backstage at a Band of Brothers concert. Can she save the day - and will her best friend ever forgive her if she makes Band of Brothers break up?
