Rod Scher is an ideally informative and amiable companion as he follows Dana on his exciting and exhausting voyage—he places Dana fully in his time and place, offering historical and cultural contexts for the writer's experiences, observations, and expressions. Scher knows how to inspire a sense of historical imagination in his readers, without forgetting who we are now. Scher can be proud of his own achievement in bringing such factual detail and humane judgment to this edition.
