One night of every year, all book characters gather in their kingdom and home - Dara. Good hold a masquerade, a ball of sorts. Evil... nobody really knows what they do. It's assumed they simply make the most of their freedom. This night is every character's favorite, because it's a chance to let loose and be free from the stresses they face in their stories. Until one year. When people begin disappearing, three characters step up to the challenge. Can Leo Valdez, Christina Torres, and Ginny Weasley - three characters thought only to be supporting - save their friends? Will they be able to show a fighting side of them, or will their world be ended forever?
