I've been getting into SF over the last several years.
My favourite writer beyond a doubt is Philip K Dick: I've read over 20 of his books, and aim to eventually read everything he published.
Other writers I like: Octavia E. Butler (Lilith's Brood/Xenogenesis is amazing), Margaret Atwood, John Wyndham, Doris Lessing. Of the newer breed I like Ian McDonald, Maurice Dantec, Paolo Bacigalupi.
Recently been getting into China Mieville.
What do you read/recommend?
