I nominated Samuel Delany's Dhalgren. It's a circular post-modern science fiction tour de force, a novel that seems to be writing itself and ends with its beginning. It stars The Kid, an amnesiac half-Native American with one shoe who wields a Wolverine-like string of blades called an orchid and spends most of the book trying to figure out what the hell he should be doing and whether he wants to be a poet or a fighter while weird shit happens all around him.
