I had a look on Amazon UK a few days ago, and was surprised to see almost nothing by Zelazny for the kindle, just a few collaborative works and sequels-by-other-hands. That's quite disappointing for such a significant writer. I wonder what the problem is.
I have Lord of Light in my TBR, in paperback. It's one of the 8 Hugo winners I still have left to read. I'm kind of saving it so I have some motivation to read the more off-putting ones first.
