I feel kinda bad just linking to other stuff I've written, but Pizzeria Kamikaze really is a good graphic novel and I want you to know about it. It's a fantasy story about life-after-death. Or, more specifically, life-after-suicide.
By the way, a movie's been made of it. Wristcutters: A Love Story debuted at Sundance this year and gets an 83% fresh rating at Rotten Tomatoes (that's 5 out of 6 critics who liked it, which isn't a big sampling, but still...). I'd love to see it when it starts making the art theater rounds.
And if you're interested, both Pizzeria Kamikaze and Wristcutters are based on the short story "Kneller's Happy Campers," which appears in author Etgar Keret's collection The Bus Driver Who Wanted to Be God & Other Stories.
