Reborn: Apocalypse Revenge

Zombie apocalypse broke out. My boyfriend stole my supplies, ran off with his sweetheart. Lucas Langdon rushed to save me, but died. I was reborn before the outbreak. I stockpiled, saved Lucas, and locked my ex-boyfriend and his sweetheart outside. A heatwave apocalypse descended. A mysterious person claimed obedience brought cooling; 'obedient' people froze to death in the heat. My parents disappeared, leaving a note: 'Don't trust anyone.' I set off to find my mother.
