I've actually just started to get back into reading seriously after an extended hiatus. I picked up a bunch of Kurt Vonnegut's stuff and I'm loving every moment. I've read Slaughterhouse 5, Cat's Cradle, Mother Night, Sirens of Titan and Breakfast of Champions thus far. It's too hard to pick a favourite from that bunch.

Vonnegut aside, my favourite novel is probably House of Leaves by Mark Z Danielewski. I say 'probably' because there are a bunch of good books I'm well overdue for a re-read of.
