The weekend Mya had turned 21, after an experiment had gone wrong, an outbreak swept across the world, killing all of the sick, dying and fatally wounded, over half the population. Wars and riots broke out afterwards, people fighting and killing for food and survival. Mya eventually found herself alone at an abandoned cabin in the mountains. Years passed by and she began to realize she no longer aged, never got sick, and although she had never been seriously injured, she still healed unusually quickly. She wasn't sure if anybody else had survived until four strangers suddenly changed everything for her and opened up a whole new, terrifying world.
