I haven't read Gene Wolfe, I'm a little skeptical of reviews by fellow authors (some of that is pay for play), the publishers like to be able to publish hyperbolic praise by well known authors on the backs of book jackets.
That's not to take anything away from Mr. Wolfe. SF is one of my genres of choice, so maybe I'll have to snag a copy of "Book of the New Son."
I like convincing, complex characters & complex, mind-bending plot lines. Some of my favorites are JRR Martin (still waiting for Godot... I mean, the next book in the series...), Gary Jennings, Neil Gaiman, Rudyard Kipling.
