I read this book at age 13, after loving the other Carl Hiaasen books when I was younger. I have learned about science, Florida ecosystems, monkeywrenching, and environmental protection from these books. In Chomp, I could not find an exact age for the main character. There are mentions of romance, but it's not an issue. This book does expose the reality of reality TV: staged, scripted, produced. Violence, drinking, and poverty are prevalent. The two young characters are in peril at times, and people are injured by purposeful gunshots. One girl is abused by her alcoholic father, who drinks during the book. I would say that this book is a go for age 10 and up, but make sure that the reader is aware of poverty and violence in rural areas.
