"Dear Marcus" is a self-published first book by someone with no connection to New York publishing. At the age of twelve its author, Jerry McGill, was shot in the back in Manhattan's East Village on New Year's Day by someone he never saw. He has spent the rest of his life in a wheelchair. (As with O'Rourke the anniversary of his tragedy is a holiday and unlike O'Rourke he gives himself a treat every year--a fancy meal at a restaurant, a trip to London.) His book is subtitled "Speaking to the Man Who Shot Me," and since this man was never found McGill gives him a made-up name and then cries out to him about his life.
