Zelazny’s Amber. You recomend?

Hell yeah, give it a go. Not everyone's cup of tea, but if you like it you tend to love it. It's a product of the 70s, and Zelazny has a particular prose, economical, broad brush strokes that leaves the reader to fill in the details with imagination, each reading unique.

Some dislike the second quintology. I think it's not as good as the first and faded, along with the author's life, at the end, but I liked it and bad Zelazny is IMO better than most out there. G.R.R. Martin and Neil Gaiman (yeah, I know, dick, but competent writer) both cite him as a major influence, and he has all the Hugos etc.

If you want to try something else by him first, A Night in Lonesome October is special, one chapter a day. I (most years) and others start on Oct 1 and read a chapter a day, does not disappoint.
