That’s Gross by Crispin Boyer is about lots of icky things that people would not naturally do on a daily basis. It can go right from eating insects to having parasites in your hair. If you like weird things, you would definitely enjoy this book.
I liked this book because there is a ton of humor and excitement in it. I would recommend this to anyone my age or grade which is 12 or 13 years and between that number range and either 7th or 8th grade or lower. If you like the world record books you will definitely love this book.
