8) The Saliva Tree, by Brian Aldiss

Actually a collection, including the title story which shared a Nebula with Zelazny’s “He Who Shapes” (later expanded to The Dream Master). Several of the stories are non-sf – two about serial killers, whcih slightly surprised me, and one about the death of the medieval Serbian ruler Vukasin Mrnjavcevic. All exceedingly good stuff if you like your Aldiss, which I do.
