Volume 2 takes place years after the original Snowpiercer and follows generally the same plot as the first book.  A lower-class grunt bucks the system and falls for a woman above his station.  Legrand opens the world up a little more in these new installments, revealing things about the past, pushing the story into the future, and offering fresh insight and commentary into the nature of societal castes, power, and humanity itself.
The writing feels derivative, at times, and even clunky (but that might be the translation from French to English), and, in many ways, it is Rochette’s art that is the star of this series.  Rochette’s blue and grey painted covers convey a sense of innocence and mystery that pervade this title.  The interior art, while less refined, is nonetheless potent, detailed, and expressive.

If you enjoyed the first installment, you need to check out Snowpiercer Volume 2.  This is a powerful and penetrating look at Western culture and an excellent follow up to the original series.
