My 5 year old brought this home from her school library. I don't know when it's OK to throw out words like "evil" and "devil" and then say it sounds like a great idea. If you want to explain to your small child why Halloween is messed up at it's roots, this is the book for you. This is a book I would pick right before I tell my kids that we don't celebrate halloween. Don't let the cute pic's fool you...or your kid.
