The world ends on May 2nd, 1983.
Mary Winchester dies in a basement lit by gas lamps, in a storm-worn house on an otherwise quiet street in Lawrence, Kansas. Lightning strikes neighboring houses, setting brushfires in nearby fields. In time, the whole city will burn. She leaves behind a husband and a four-year-old son, to raise a newborn in a broken world.
Against all odds, Sam Winchester survives. He knows nothing but life on the road, moving from place to place, settlement to settlement. Endless days of walking, setting up camp, hunting in the woods for meat and stealing the rest. Fuel is more precious than ever, and rarer still. Ammunition has become the new currency. The world is slowly piecing itself back together, alliances forming and new borders being drawn, but times are more dangerous now than ever.
Sam turns twelve years old, and everything changes. Roses bloom in his path. Birds follow him, watch him. Sam feels a power in him that he doesn’t understand. The power to heal, the power to control. But also the power to destroy. Sam is forbidden from exploring this power, from questioning it, and the Winchesters stick to the fringes of this new world more now than ever.
Years pass. Sam’s power goes dormant, becomes little more than a dream of his youth. He is twenty-two years old, and the road has claimed his father’s life. Sam and his brother Dean continue on alone, wandering what was once the American Midwest, but is now a vast territory patrolled by well-armed militias. Moving goods from place to place in exchange for food and weapons, evading capture by soldiers and thieves alike, life has settled into an odd sort of routine for the brothers.
That is, until a chance meeting with a psychic in a refugee camp leaves Sam reeling from memories of his forgotten childhood, and visions he barely comprehends. Ignoring Dean’s protests, Sam sets out on a journey alone to discover the truth, and in the end finds himself face to face with his destiny.
