Albion's Ransom II: Worm of Sixty Winters (2013)

From publisher blurb:

Worm of Sixty Winters is a full-length campaign for The Esoterrorists. It works as a stand alone adventure, or as the sequel to Albion’s Ransom: Little Girl Lost.

An Esoterrorist weather control ritual has brought sudden blizzards and extreme temperatures to an unsuspecting England. This they hope will be the first stage of the Fimbulvetr of Norse mythology – a dreadful winter that lasts three full years and heralds Ragnarok, the Viking apocalypse.

You are the American team – brought in as experts in your field – that failed to stop that ritual.

Now only you can prevent the Esoterrorists from causing irreparable damage to the Membrane. In a hazardous chase across a snow-covered Britain, facing sinister cultists, terrifying bikers and ordinary people taking desperate measures to survive the extraordinary circumstances, you must use all your resourcefulness just to carry on.

Featuring additional adventure seeds by Matthew Sanderson which focus on individual tales of horror to personalise the impact of Britain under snow, Worms of Sixty Winters allows your players to fully experience the breakdown of society in the Esoterrorists’ greatest threat to the Membrane.

Given one final chance to make things right, can you prevent the Esoterrorist plot to unleash Fimbulvetr?
