The Explorers (Snow Piercer, Bk. 2)

Coursing through an eternal winter, or an icy track wrapped around the frozen planet Earth, there travels a train that never stops. This is Snowpiercer: one thousand and one carriages long. The last bastion of human civilization. Or is it?

A second train travels through the snow on the same track, its inhabitants living in constant fear of crashing into Snowpiercer.

And from this second train, a small group of scavenging explorers emerges, risking their lives in the deadly cold . . .
