A quick post to suggest some really good titles for Halloween.
For younger children (and older children as well, as I personally enjoy this book myself), I really recommend The Witch Who Was Afraid of Witches by Alice Low. This is a really good friendship and confidence book, with a lot of fun Halloween images. A great book I discovered this year is Vampire Boy's Goodnight by Lisa Brown. This book has some especially wonderful references to classic monsters and the legend of Dracula. I would also recommend Moonlight: the Halloween Cat by Cynthia Rylant, especially for its wonderful, calming tone.
