Every winter, the human population hibernates. During those bitterly cold four months, the nation is a snow-draped landscape of desolate loneliness, and devoid of human activity. Well, not quite. Your name is Charlie Worthing and it's your first season with the Winter Consuls, the committed but mildly unhinged group of misfits who are responsible for ensuring the hibernatory safe passage of the sleeping masses. You are investigating an outbreak of viral dreams which you dismiss as nonsense; nothing more than a quirky artefact borne of the sleeping mind. When the dreams start to kill people, it's unsettling. When you get the dreams too, it's weird. When they start to come true, you begin to doubt your sanity.
