I read this book at school because the three reading teachers split up their classes and I got put in The Sisters Grimm group. The book is filled with a lot of popular fairy tale characters and some unpopular fairy tale characters. If you do read The Sisters Grimm then you should probably start with book one or if you can easily find out what is going on then you can probably start with book two. If you like fairy-tales but you also like chapter books then I recommend The Sisters Grimm book because it's a fairy tale chapter book.
