i chose this book for two reasons. one much more important than the other. the first was because there were ninjas in the title. the second was because there were piranhas in the title. the ninjas were more important. i really like ninjas. this book has nothing to do with ninjas. not really. and the piranhas are peripheral. i did know that before i started reading though. i'm not completely foolish. i did read the back. what this book is about is a trio of middle school students who attend the prestigious peshtigo prep. there is elias who must deal with the high expectations of his genius family, shohei, whose adoptive family has decided to immerse him in the culture of his ancestors, and honoria, whose science fair experiment involves teaching piranhas to become vegetarians. in a school that has a reputation they find that finding the truth isn't always easy, even when it's in the name of science.
