She interacts with the good, the bad, and the downright dirtiest of spirits, ghosts, and a few demonic beings. After coming home to find her abusive foster parents being tortured by a demon, she's saved by an angel with news from heaven. The apocalypse has started, and she is destined to stop it. So when Glass finally realizes she must try, The Four Horsemen, Pestilence, Death, War and Famine meet her, and all four brothers fall in love. Will they fight for her love? And if they do, who will win? How much damage will they cause before they destroy everything in their paths?
