Diary of a 6th Grade Ninja 10: My Worst Frenemy

Age Level: 9 and up Grade Level: 4 and upThe name's Chase Cooper, and this is my tenth diary as a 6th grade ninja. If I had a penny for every time trouble came knocking at my door... I'd have ten pennies. A few days have passed since the green ninja clan appeared, but that's more than enough time for them to give me a headache. It doesn't help that my attention is stretched between a crazy robotics competition, an annoying pirate poser, and the ex-leader of the red ninja clan. Somehow Wyatt and I have found ourselves on the same side of the fence this time, but we've made a deal - if I help him get his ninja clan back then he'll leave me alone forever. Now Wyatt and I are on a mission to figure out who the leaders of the new ninja clans are, but working with Wyatt definitely isn't easy. Whoever said "keep your friends close, but keep your enemies closer" obviously never met Wyatt.Diary of a 6th Grade Ninja 10: My Worst Frenemy is a hilarious action adventure that's entertaining for children ages 9-12, middle school students, and adults.
