This is an entertaining story and you don't need to read the 27 books before this. It's independent. If you know the story of the Piped Piper and the rats and the plague, then you'll enjoy this rendition. I love that a group of rats and a cat become self-aware. It's smart and funny. Would I put it in a high school library? Probably not but it's perfect for a public library. It's quirky. If you like Doctor Who, or Hitch Hikers Guide to the Galaxy then this book is perfect for you.
