Cheryl Morgan over here has something interesting to say about what science fiction readers want when they read fantasy (basically lots of sensawunda ideas).
She is commenting on how some series/trilogies (with reference to The Shadow of Tyr, book 2 of The Mirage Makers) tell you all about the world, and then the remaining books are focussed more on the plot and the characters, and therefore perhaps of less interest to a certain type of reader.
There are also some interesting reader comments following the post.
I must say that I always thought Cheryl to be one of the best reviewers around when Emerald City was extant, because she was very good at giving the reader an idea of whether they would like the book.
Oh my, and I see I shall have to be on my best behaviour at Worldcon …. help!
