King City [PDF ebook] 

A slacker with a weaponized cat goes up against deadly drug kingpins in “this bit of tongue-and-cheek third-generation fight manga . . . wondrously fun” (Publishers Weekly). When the whole world seems insane, where does true madness lie? In King City, that's where. And Joe is no crazier than anyone else. A young man with no home, no purpose, and almost no friends, Joe does have one thing going for him—a very special cat. With a simple injection, Joe's cat can be anything: a weapon, a tool, or even a cuddly companion. But what – if anything – can transform Joe?  Whatever it is, it can probably be found in King City, an outrageous semi-futuristic city full of spy gangs, alien porn, and reasonably priced diners. A word of caution: Avoid the meatloaf.
