Y the Last Man is an AMAZING comic series under DC's Vertigo imprint. It's collected in Trade paperback format now, and it proves that comics as literature did not end with Gaiman's Sandman. Right now m'self, I'm reading Perdido Street Station, by China Mieville. AMAZING pseudo-steampunk fantasy. Depressing as all hell, but gloriously wonderfully so. And the other books in the same universe, The Scar, and Iron Council are even better. I've read my copies of each till they're nigh falling apart.
