I Shall Wear Midnight is supposedly that last novel about the young witch from the Chalk, Tiffany. In some ways that knowledge colors the book.

Tiffany has done with her education and is back home serving as the Chalk's witch. Sadly, strange things seem to be happening, more than just what happens with an senient cheese named Horace, a lawyer who is frog (but who can be paid in beetles) and the Feegles around.

In some ways, the novel feels like a good-bye, if not to the Disc than to Tiffany. This makes the novel a little bittersweet in tone. It also isn't quite as tight as Nation or Unseen Academicals. It also feels like Pratchett is showing writers like J.K. Rowling and others that fantasy can be more than just magic. The story takes left turns out points that can be shocking or, to be more extact, might make parents uncomfortable. Yet, considering Pratchett's sheer knowledge about folklore and folktales, it could be said that he is returning fairy tales and fairy stories to thier original purpose.

And there does seem to be something deeper in the book than the simple plot. If Nation was about belief and community, then this book too is about community, but also about acceptance. Tiffany's battle in the book isn't just acceptance of others as her as the witch, but also her need to accept what others are.

For the long time Disc fan, several loved characters make appearances, including various witches and members of the Watch.

The book is a fitting conclusion to the Tiffany sub-series. It has been a pleasure watching her grow up.
