The Faded Sun trilogy was released as an omnibus within the past two years. I saw at at Borders, before they went under.
It seems to me that everything Cherryh does is terrific- she appeals to my mind more than many SF or fantasy authors, who seem most inspired by the publishers' ideas about what sells. They are dead wrong about who SF fans are, so we get poorly conceived fantasy and shoot 'em up SF.
Have you read any of her "Foreigner" series?
Chanur is so good that I occasionally reread it. I love the way she uses psychology or behavior science as her jumping off point and uses different alien psychologies to dictate the way their encounters with each other turn out.
Who else do you like? Have you read Charles deLint? Sherri S. Tepper?
Hope to hear from you soon, fellow reader!
