...is a contemporary fantasy novel that would basically be a Mamatasian mash-up of Nick Hornby's "High Fidelity" and Robin McKinley's "Sunshine," or (to blatantly mix mediums) of BtVS and Questionable Content. Basically, the characters would sit around drinking coffee and arguing with each other about the respective merits of various obscure Indie bands, except when they'd be occasionally interrupted by hordes of vampires or demons that needed killin'.

Just to be even more self-indulgent, I'd be tempted to make one of them a philosophy grad student so they could also sit around talking about the cosmological argument and the tenseless theory of time, but I'm afraid that might get silly.
