I bought this inexpensive ebook early on when I was researching the 1920s for my novels. In retrospect, I could have saved my money, even though I did pull a couple of useful facts out of the book. It was just too short, with too little (and too generalized) information -- it was essentially the Cliff Notes of history books, although I didn't know it at the time. It might be a good source of information for someone in middle school or high school who is doing research for a project, but for anything more, it just doesn't give enough information.
Short books equal short reviews I am afraid, so that's all I have to say about this one!
