(I'm more on the writing side, rather than the reading, as I don't like 'polluting' my mind by reading other people's books while I write primary chunks of my own work
!)
I haven't read much of his work but I have got
The Last Legends of Earth which I have to say I adored. Big multi-universe stuff, big eras of time, big interconnected stories. Why I haven't got round to reading anything else of his...is a mystery. I think at the time I then found PKD, Dickens and
Dune and a whole bunch of other stuff. (There just isn't enough time in the world to even finish the books that are already published, and here I am trying to add more...)
What of his books do you recommend?
