QUOTE : As the book progresses, it takes on a more and more unstable character — filled with unpredictable associations and departures, marked by increasingly rapid shifts in tone — until you reach a point where you feel the whole thing being to levitate, to rise ponderously off the ground like some gigantic weather balloon. By the last chapter, you've traveled so high up into the air, you realize that you can't come down again without falling, without being crushed.
