Available to pre-order now!

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

Nobody knows how to survive the rough and tumble halls of middle school better than Greg Heffley. In fact, he's got a three-ring binder chock-full of notes on his school's biggest bullies—along with his hard-earned strategies for how to outsmart them.

But when Greg's binder falls into the wrong hands, his world starts to unravel. Now it's a race against time before the bullies discover the identity of the person behind it.

Greg has learned to roll with the punches, but now he's backed into a corner with no good options. Will he throw in the towel, or go down swinging? One thing's for sure—Fight or Flight is a knockout!
