Found In Destruction

The world hangs by a thread. Everything we know and rely on could be destroyed in the blink of an eye, and everyone thinks I can save it.
But how can I save the world when my heart is shattered by four men who said they’d always love me?
How do I bring down a ruthless leader and his followers when he lurks in the shadows?
How can I be the hero they need me to be when I’m the villain they’ll fear the most?
It is worth saving the world when it’s already too late?
