Twelve-year-old Matt Sprouts is in big trouble. He didn't mean to hurt his neighbor Jenna with that awesome ninja move, it just happened! Blame it on morning cartoons or Jenna's lack of coordination. Anyways, getting grounded is the worst thing that could happen, right?

Wrong.

After the ninja incident spirals into a series of downright unfortunate events, it's decided that Matt has contracted the Curse, a hometown myth that has ruined the lives of middle schoolers before him. And as if the Curse weren't enough, entering sixth grade proves to be just as mysterious-his first job, a strange girlfriend, insane teachers, and soccer tournaments bring more problems.

Finally, his life's unpredictable path leads Matt to take matters into his own hands. To put a stop to everything, he calls upon awkward new friends, bumblebees, the Purple Grape Lady, crutches, and a few other tricks to attempt the impossible: break THE CURSE!
