This is the second story in the Unspeakable Things series. The story picks up where the last left off, with Quentin thinking maybe he's come out ahead, but discovering very quickly that things are about to go downhill for him again, and fast. He's made enemies a guy like him doesn't want, and they don't seem to be the live and let live types. Vegas stars as the setting for this story, but its a vegas filled with objects of power, with rips between this existence and another, with a shadow government and a great many people out to poke Quentin full of holes. Fatal holes.
This story is fast paced, well drawn, and utterly enjoyable. The next in the series isn't out yet, but when it is released, I will be picking it up.
