Ember Road

A gray fog swallowed the world and devoured the sanity of most people. Power went out, networks were severed, and survivors scrambled for survival among the ruins. The dense fog accelerated mutation and magnified the good and evil of human nature. There are no superpowers, no bloody sensationalism—only a group of ordinary people huddling together for warmth in desperate times. On a wasteland where order has collapsed, they use teamwork as a shield and humanity as a blade, searching for a glimmer of mutual redemption in the endless gray mist. — Description from novelcodex.org
