"An excellent book. In its sharp imagery, its clever inferences, its suspense, its characterization, and its occasional grotesque humor, it stands favorable comparison with its great model by John Bunyan." — Chicago Tribune
"The allegorical characters are not just abstractions. They are, in every instance, people objectively real and subjectively true to the inner meaning. The language throughout is plain, straightforward and leanly significant. To many it will seem like a fresh wind blowing across arid waters." — New York Times
