Extinction Cycle

When a man-made viral bioweapon escapes a top-secret lab, the world faces a crises unlike any it’s ever known. Within months, billions die, viruses spread, and the human race teeters on the brink of extinction. Faced with complete annihilation, scientists release a new bioweapon that kills ninety percent of the infected population, but the remaining ten percent transform into even more terrifying creatures called Variants. These monsters evolve into the ultimate predator, with the ability to see in the dark, heal quickly, and climb walls.

Throughout the world, men and women band together to fight the evolving monsters in an effort to save humanity. You are invited to tell the stories of these heroes who stand their ground, stories of battles where thousands lose their lives, stories that explore the human spirit—defiant against overwhelming odds, fighting to take the world back from the monsters and the government that accidentally created them. Welcome to the Extinction Cycle World, where no character is ever safe.

  2. Create High-Quality Works: An excellent customer reading experience is paramount to Kindle Worlds. Poorly formatted books and books with misleading titles, cover art, or product descriptions will not be published. We reserve the right to determine whether content provides a poor customer experience.
  3. Promote Your Creative Vision: Your writing and vision should be the focus in your Kindle Worlds fiction. Paid advertising or excessive use of brand names is prohibited.
