Query: Disappointing

After reading "The Monkey Wrench Gang" and his opus "A Fool's Progress", I was let down by this particular Abbey effort. The cliched character of Burns, the beleaguered cowboy, riding out of the purple-hazed past to rescue an old buddy from the perils of modern times, is shopworn at best. Abbey's prose, usually spectacular, just doesn't seem up to his standards here. Missing, too, were the pyrotechnic polemics that make Abbey so much fun to read. The ending was so thoroughly telegraphed, I felt slightly insulted. Avoid this book, and read "A Fool's Progress", Abbey at his finest.
