Jam by Ben "Yahtzee" Croshaw
For the uninitiated, Yahtzee is a video critic of the ever popular "Zero Punctuation" video series on the Escapist. Very funny guy who says a lot more about a game with his brand of humor than a lot of others say in their more professional reviews. His first book,
Mogworld, was a pretty spot-on riff of
World of Warcraft and some fantasy tropes, and was very funny, especially if you're a fan of Douglas Adams or Terry Pratchett.
Jam is still as funny, but removed from a fantastical world and planted in a more contemporary one, where humanity is under attack from carnivorous jam. Yes, jam, the stuff you put on toast.
