Recommendations?

So given the predilictions of those of you on my friendslist, most of whom seem to be avid SF or fantasy readers…

Have any of you read C. J. Cherryh’s Cyteen? What about C. S. Friedman’s Cold Fire trilogy or Tad Williams’s Otherlands books?

I know I’m going to like the Tad Williams books. And an old friend kept insisting I needed to read Cherryh. (Actually, I agreed with him because I started to read Downbelow Station years ago, and I think I just never finished it because of a lack of time. But I’ve never heard of C. S. Friedman.

Thoughts? Opinions?
