I mean... by structure do you mean the usual trappings of crappy mass-produced fantasy that can't think past Tolkien (i.e., dwarves, elves, fighting A Great Evil) or more the Campbellian structure? Because finding books that don't fit the former is easy; finding books that don't fit the latter is really hard in every genre of literature.cynicalandbored said:Show me a fantasy book that isn't heavily based on the same structure as a million other fantasy books and I'll give you a medal.
But hey, have a few excellent, atypical novels:
-Perdido Street Station, China Mieville
-City of Saints and Madmen, Jeff VanderMeer (this is sort of cheating; it's more a collection of stories, but it's brilliant and atypical and original and I can't say enough good things about it)
-the Gormenghast novels, Mervyn Peake
Edit: oh damn, I forgot a really good one
-House of Leaves, Mark Z. Danielewski -- if I'm being honest it's really somewhere between SF/Fantasy/Horror, but it's definitely pretty unique.
