To be truthful I did not like this book at first. I am a mature librarian. I asked myself why would a young girl go camping with three boys. I kept reading this story and could not stop. The storyline was really intriguing. The characters were well developed. Characters I did not like at first, became likable. Again, being an older reader I thought that I could not recommend this book to a middle school student, but I was wrong. The language was a little crude, but not offensive. Great adventure and realistic mix. I will recommend this this book to people looking for a adventure and thought provoking story.
