The last book I've read (which I just finished last night) was
Soon I Will Be Invincible by Austin Grossman. Great send up of the comic book genre, the story is told in alternating chapters by the mad genius Doctor Impossible and the relatively new superheroine cyborg Fatale.
Before that I was reading Mario Acevedo's books (The Nymphos of Rocky Flats, X-Rated Bloodsuckers, The Undead Kama Sutra). I am eagerly awaiting his fourth book, so far the series has been great and I agree with the blurb on the back of one of them, "Anne Rice meets Dave Barry." It's the ongoing story of a vampire private investigator who gets called into the weirdest supernatural cases, that tend to involve military secrets, drugs, aliens, nymphomania outbreaks, the porn industry, Indian mysticism, and more aliens.

Also, if you are a William Gibson fan, Pattern Recognition is a very interesting book set more in our modern day than some far cyberpunk future. I enjoyed it a lot. What would it be like to be allergic to trademarks in our present logos for everything age?
