Anti-Christine and the Four Unicorns of the Apocalypse

So, Christine is the Devil's daughter, which makes her the Anti-Christ. And at the age of thirteen, she was supposed to fulfill her destiny and end the world. Obviously, Christine didn't do that... Instead, she did what any rebellious teen daughter of the Devil would do--she took her father's gift of the Four Horsemen of the Apocalypse and turned them into unicorns. Then she decided she didn't want to end the world, so she took her new friends, ran away from home, and started a rock band. But now she's twenty-seven, and the Devil, during that time, had another daughter—who is about to turn thirteen. And the only way she can fulfill her father's wishes is to find and kill her half-sister: Anti-Christine and the Four Unicorns of the Apocalypse!
