Batman: No Man's Land - Devin K. Grayson & Bob Gale

A great slice of Batman fun in which Gotham's population is reduced to a few stragglers who form clans and go around fighting each other and marking their territory with spray paint. As it turned out, a great follow-up to High Rise. The characters don't spend too much time waxing philosophical (or sociological) about their situation, and when they do it's well-written and interesting. And the Joker stabs someone in the neck with a fork.
