Jam by Yahtzee Croshaw
It's a post-apocalypse novel about an organic eating strawberry-like jam substance that invades Brisbane Australia. So far it has been pretty funny and well written, but I'm just about half-way and I'm kind of wishing it was over. The main character has literally no personality, which is an active part of his character arc, but it still makes for hard read when there's just nothing there. Still if you're a fan of Terry Pratchett or Douglas Adams, you'll get a lot out of this and his previous novel,
Mogworld.
