I'd been meaning to follow up on this almost since it was posted, but I didn't want to steal Zach's thunder. About a month ago, he had asked people how they had first encountered Zelazny's works.
I thought it was an interesting question and worth its own post, so here it is. I touched on my own introduction in my Roadmarks post, and I'll reproduce it here.
My father's girlfriend lived down the street from us when I was about fourteen or so. I was at her house one day in the summer, looking for something to read, and she gave me her ex-husband's shoebox full of sci-fi paperbacks. I grabbed two that looked nifty, Roadmarks (aka Last Exit to Babylon) and Creatures of Light and Darkness.
I loved those two and I was hooked from then.
Also, I don't have any contact information for you Zach, but you contribute to the site with quite a bit of Zelazny stuff, so if you want to have author privileges in order to post these things yourself rather than just putting them in the comments, just drop a line and I'll make it happen.
