You mean, has anyone here read "Kane"? The answer is - me. It's one of my favourite fantasy books ever, and I mean ever. I first read it when I was a teen, in an absolutely atrocious translation, and it still got me hooked. I bought the books (which was rare, at that time I used the library - my parents did not have much money or space in the flat), kept them ever since. Recently I got hold of English originals, read them again, this time with all my literary background that had accumulated ever since, and boy, while I remembered all the stories very well, I discovered a lot more in them.
First of all, Wagner thought of himself more as a horror writer, so "Kane" is not your simple sword&sorcery - and if a novel starts with a motto from Lovecraft, you know what to expect (as a teen I did not, as I hadn't read Lovecraft then). And then there is a story which is set in a place that is basically a fantasy version of WWI on Western front. In addition, he was trained as a psychiatrist, so his characters have a lot more psychological depth than average in this genre.
And the main character is an evil bastard. A likeable evil bastard, sometimes, but evil nonetheless. If he fights greater evil, he does not do it to save mankind or anything - it's just that the other side interferes with his plans.
However, if you want to read it, there is just one little problem - it's damn hard to get the books legally, unless you want to pay $175 for this edition:
