In no particular order,
- Kurt Vonnegut, Cat's Cradle
- Albert Camus, The Stranger
- J.D. Salinger, Franny and Zooey
- David Foster Wallace, Brief Interviews With Hideous Men
- Milan Kundera, The Unbearable Lightness of Being
- Haruki Murakami, 1Q84
I can't pick a single title for Camus or Vonnegut, but those two respective titles are near the top.
