When the going gets tough, what’s a wimpy kid to do?

In Fight or Flight, Greg Heffley faces his biggest challenge yet as he becomes a target for the school bully. Luckily for Greg, his best friend, Rowley Jefferson, takes karate, so at least Greg’s got someone in his corner. But an unexpected twist makes Greg realize he’s facing an uphill battle.

Will Greg step into the ring or throw in the towel? One thing’s for sure―Fight or Flight is a knockout!
