Fading into Darkness

When two girls decide to summon a spirt things go wrong. Not like they can stop it. The world they live in turns to darkness, by the only one thing that could prevent it to. Jake, the spirt they summoned. "With power like this, wouldn't you want the same thing?" He mocks to almost everyone. Kailie, a 16 year old girl who dislikes Jake, wanted to get rid of him. Not kill but trap him back in the hell where he belongs. Jason Hooks, a man who the mom suggest to help them doesn't do anything but fail at helping them. The only one who can help is Michael a angel.
Two things are preventing the world from falling apart and that is the love that two people hold for different people. The world turns to darkness and the whole human world goes completely insane. Who will survive? Will Jake vanish? Will they get helped? Is holly the one to blame?
