"Catch-22" by Joseph Heller is a darkly comic novel set during World War II, following Captain John Yossarian, a U.S. bomber pilot desperate to escape the madness of war. Trapped by the absurd Catch-22 rule — that trying to avoid dangerous missions proves he's sane and thus ineligible to be relieved — Yossarian battles bureaucracy, illogical rules, and the insanity of military life, all portrayed with biting satire and surreal humor.
