I first read it as Le Transperceneige, and despite my poor French liked the idea but confused about the later dialog. Re-reading in English as The Escape made things somewhat clearer. Didn't realize there was a film and never saw it, nor did I bother reading the remaining volumes (Explorers, Crossing and Terminus). Escape's ending was good enough, if grim.
Libgen has both original French and English scanlations.
