23-please forgive me Terry Prachett

I just finished this book

and I thoroughly enjoyed it.  It lived, like most of the Discworld books I've read so far, in my bathroom, for use while taking a long hot bath, or to prevent the waste of time while performing other...um...activities.
Why yes, I do have ADD, why do you ask?

Anyway, this book is a concoction of  Mr. Pratchett's trademark irreverent humor, and the classic "Pied Piper" fairy tale.  I laughed all the way through this book.  It did get dark at times, but it was very very enjoyable all around, and the end was very amusing and rather unprecedented, as far as  rat stories go.   Things  I learned along the way:
    - Mr. Bunsy's adventure would be a very funny spinnoff story, and a good send up of Beatrix Potter.
    -Cats do not have a deity (it would be too much like a job) but they really do have 9 lives
    -Kevin is not a good name for a fairy tale hero, especially one who is an orphan, of unknown parentage, who may really be a king, or magical or whatever.
    -Terry Pratchett has a very, very big and twisted imagination.
Good Potty read though :)
