My name is Chase Cooper, and I'm a 6th grade ninja. It's my first day at a new school and the only person I know is my cousin, Zoe (but she might be a little too cool for me). I was just another scrawny kid until a group of ninjas recruited me into their clan. It was a world of trouble I wasn't prepared for, which is why I kept this diary (or 'chronicle' as my dad would call it) to warn other kids about the dangers of becoming a ninja. They say history is destined to repeat itself...well, not if I can help it.
