If you loved the absurd and biting wit in Breakfast of Champions, you'll find Catch-22 just as uproarious and sharp. Heller's portrayal of Captain Yossarian and his fellow airmen is packed with surreal humor and satirical takes on war and bureaucracy that echo Vonnegut's approach to American culture and its contradictions.

Slaughterhouse-Five is another of Vonnegut's classics where he breaks the fourth wall and plays with the conventions of storytelling—just like in Breakfast of Champions. The novel’s self-aware commentary, author intrusions, and Billy Pilgrim’s time-hopping create a reading experience that’s as unconventional and thought-provoking as you’d expect.

If you appreciated the way Breakfast of Champions contemplates the meaning of life, free will, and American consumerism, you'll be drawn to White Noise. DeLillo’s Jack Gladney navigates an absurd, media-saturated world while pondering mortality and identity, offering the same kind of existential musings and darkly comic insights.

If you were fascinated by the flawed, ethically conflicted characters in Breakfast of Champions, you'll find Mother Night compelling. Howard W. Campbell Jr., the protagonist, is both a Nazi propagandist and an American spy, forcing you to constantly question his motives and morality in the same way Vonnegut challenges readers’ sympathies elsewhere.

If the outrageous, darkly comic tone of Breakfast of Champions was your thing, A Confederacy of Dunces delivers in spades. Ignatius J. Reilly’s misadventures in New Orleans are packed with ridiculous situations and biting satire, making social critique hilariously entertaining.
