From the cover:
Life's a Bitch... and then you die. Or at least, SOMEBODY dies. Most likely, when you enter the shadowy world of 100 Bullets, it's a whole lot of people. That's just what a young man named Loop is about to find out. With a gun and 100 rounds of untraceable ammunition -- courtesy of the mysterious Agent Graves -- he's set to meet the father he never knew, and find out first-hand what the underworld is really like. It's going to be worse than he could possibly imagine.
