My name is Chase Cooper, and I'm a 6th grade ninja. The scavengers are back, and if you've followed my story up until now, then you'll know it's not all gumdrops and lollipops over here. If it were just the scavengers, I might've been all about the challenge, but this time they've brought their leader--an eighth grader named Victor. He's everything that Wyatt is, only a bajillion times worse.

The name's Chase Cooper, and this is my eighth diary as a 6th grade ninja. After having the worst week of my life, you'd think I'd try to relax and maybe stay out of the limelight, right? Nope! Zoe has me in front of the entire school playing in the Spirit Week Competition that she's set up as the new president of Buchanan. The problem is that Wyatt's playing too, and if he wins, his red ninjas will become stronger than ever before. I've been recruited...

Buchanan School is holding an election for new class president, and Chase Cooper's sister, Zoe, is running. Meanwhile, Chase refuses to join a Scavenger club, who then responds by trying to ruin Chase with every opportunity. Everyone seems to hate him now, and a reporter tries to expose his secret ninja clan to the school. Worst. Week. Ever.

The day of the big science fair is approaching at 6th-grader Chase Cooper's school. Science fair projects are disappearing and found later completely destroyed. Now the fate of the science fair rests in Chase's hands.

Someone steals the book bag of 6th-grader Chase Cooper and things get worse from there. Now Chase is number one on the Buchanan School's most wanted list and he discovers the Red Ninja Clan. Ninjas never quit - and neither do their enemies.

At the school 6th-grader Chase Cooper attends, everyone is talking like a pirate. Soon there are rumors of a pirate invasion and now the entire school is in danger. Only Chase can save it.
