The author points out that people need work, something to do, something to give their lives meaning. I found this book for free for Kindle and loved it. I loved all the ties in with the Harry Potter books and looking at the characters and their need to be useful. I am anticipating the 2nd book that she says she is working on. I do recommend this book.
Yes, I know it says Toiletrivia, but I like trivia and when I was able to get these for free for my Kindle, I got them and put them on my to be read list. Recently, when I was going through the books trying to decide what would be fun, I sent this to my Kindle and it covers a wide range of topics, so I think this will be fun for the girls.
