This is the twelfth in my one-book-at-a-time bookshelf.
The final part of the trilogy brings the Riddle-Master to a satisfying conclusion.
Could I also say that whilst I am a big fan of book covers and visual representations of creative works in general I would suggest that many editions have covers that disappoint or misdirect. There are many books that I didn't read because of their covers but later discovered them to be excellent. I'm sure you know what I am talking about. Perhaps we don't give enough credit to the cover designs that work!
Don't judge a book (entirely) by its cover.
