I happened upon the blog of an artist who rendered some memorable characters from the Book of the New Sun. I always enjoy seeing art inspired by these books. It’s such a creative and visually appealing world.
Irene Gallo the Art Director for Tor/Forge books since 1994 and Starscape books since it’s launch in 2001 has her own blog that features a lot of good science fiction and fantasy cover art including the occasional cover art for some of Gene Wolfe books. So be sure to add The Art Deparment to your favorites list.
