A sixteen year old girl named Lenox Mercury Gates always had a normal life, up until now. She had a dream one night where God came to her with a message. He claimed she was the only person on Earth who could stop the apocalypse. She must kill all six of the Devil's messengers, which are urban legends from around the world, before time runs out. The messengers are disguised as people around her that she sees everyday. The choice is hers though. Kill ones she loves and save the world from crumbling or end everything. Her slow decent into madness and her own guilt are the only things standing in her way. What will she choose?
