The Four Horsemen came to our world to destroy humanity. Pestilence has come to the city where Sarah Byrne lives, and everyone she knows and loves is marked with the mark of death. Sarah is trying to save them... It's a pity that no one told her that it was impossible to kill the Horseman. Sarah's resistance infuriates Mora. The beautiful and cruel Horseman will make her suffer. But the longer they are together, the more doubt Sarah has about More's true feelings for her... and her feelings for him. She may have a chance to save the world, but she will have to sacrifice her heart.
