By taking moral and social problems seriously, and exploring all sides of issues such as capitalism, poverty, education, class relations, anticlericalism, and Catalan nationalism, it helps bring to life Spain immediately before the Civil War. This mission is aided by memorable characters, like the saintly Cesar, devout Carmen, practical Matias, worldly Julio, and progressive David and Olga. However, the book can get lost in repetitive/exhaustive cataloguing of all the various factions and their indecipherable acronyms—and it also ends very abruptly, even for a book that is explicitly Volume I.
Also a rare Spanish book (in my experience) with a heart that understands Catholicism and depicts it fairly.
