Seth Harrington can be invisible or undetectable, but he is not a superhero. The ability only works in morally grey situations; the rest of the time, he can't turn it on and off at will. He can use a movie ticket stub to buy a coffee or a one-dollar bill to pay for a cell phone. He can stop muggings in plain sight, unseen, but only with worse violence. But this only adds to his confusion about his place in the world. Still reeling from the horrors of the September 11 terrorist attacks and ambivalent about his future, Seth is at a crossroads: Can he be one of the good guys by doing bad things, or are his newfound powers part of someone else's malevolent agenda? There are no easy answers or expected outcomes in Marshall Moore's exploration of urban life and the ways that people can disappear.
