Love Italo Calvino. For people interested in getting into it, "If on a winter's night, a traveller" is probably the best place to start and isn't a tough read.
I absolutely loved both, but I think the latter might out off some folks.
But given the HN audience, I feel that "Cosmicomiche" might be a very good choice too!
It's my stranded on a desert island pick, and for good reason.
