Top 10 Obscure But Superb Science Fiction Novels

From Listverse:

Sturgeon’s Law states that “90% of science fiction is shit — 90% of everything is shit” but, even though literally tons of crappy SF gets published every year, sometimes the absolute best gets shuffled into obscurity. Here, then, are ten novels that should have been elevated far above the stink of the heap… but somehow never got the buzz they deserve.

I’ve never heard of any of these. Looks like I’ll spend some time on Amazon tracking a few down.
