Clever, entertaining, and often humorous novel - however, I can never quite shake the feeling that it's slighter than it thinks it is and that slickness is giving off a sheen of substance. The one point where this doesn't happen - after the accident and Walt - is for me the high point of the book and the only time I felt really emotionally attached to any of the characters. There's just more resonance there than anywhere else, and the rest of the novel pales a little in comparison.
