I’m not exactly sure what the purpose of this book is.  If it is trying to be informative about life in a circus, the depth of knowledge it offers is really quite shallow.  If it is trying to illustrate how to write a diary (which is kind of suggestion by the two-page spread in the back offering tips on “Writing a Diary”), then it’s modeling bad writing: this is reported to be the diary of a grown man, but he’s writing in very short, choppy sentences, showing no evidence of personal voice or fluency.  Also, even though this is supposedly a diary, written in first person, the photos used to illustrate the book keep showing a different guy.
