From rival kingdoms, Effie and Miles have been training day and night for the moment they meet on the battlefield. Yet when they first meet properly it's at a ball to collect information on one another and fate pushes them together on the dance floor. Only one knows who each other is because he has seen her around but at first he lies about his name and past. They have been told in order to save their kingdoms they must destroy the other. That night there is a plot to destroy the royal families, an arrow is aimed at Miles, and Effie moves in front of her enemy, saving his life. Effie runs toward her kingdom, but he follows her for some reason and catches her at the border grabbing her hand and whipping Effie around and asks "why?" to which she replies with "I'll tell you next time we see one another." With a wink she swipes him off his feet and she's gone.
