I have read a lot of Butler but there are times when I wonder if she was fully aware of how massively creeptastic most of her protagonists are. My favourite of hers was the first of the Parable books, but I've never re-read it and it was a long time ago.

I've read lots of Duane, including the whole YW series and Spock's World (which is awesome!). When she's good, she's very very good. When she's not very good, she's still pretty decent. Tales of Five I read a long time ago but I want to reread them; I'm hopeful they are books I'll actually get more out of as an adult, rather than having that teenage shine fall off. Was the series ever finished though? I remember it ending on a cliffhanger.

I think that's about all I've read from A-G, apart from Cherryh's Foreigner books. I struggle with her beginnings too, which is why I've never made it more than a chapter into Downbelow Station. I have a copy of the Wanderground by Gearheart, but I've never read it. (I paged through the first chapter just now; probably won't be reading it!)

I have to say, that list seemed really short to me, but I went through a few of my books; apparently I've read more from the 80s.
