Kat, Charlie, and Alora thought they'd never see eachother again until now. A strange exhibit had been put up in the Museum of Natural History in London. It displayed an absurd idea, a theory that a whole different universe was alive, running and functioning. An idea that was already thought of, however, the ideas lined up exactly with an already known and familiar world to Charlie called Ivaldah. He and his friends dug deeper into the situation, discovering and uncovering a lot more than they thought. Kat and Alora have been The Queen's Assasins for over 2 years now. But when they get sent on a secret mission, to take out the infamous Black Night of Niaradar, they stumble upon old, familiar, and in some cases, much loved faces. But the group stumbled upon a much greater evil than they ever had. Will they be able to face courage, love, sacrifice, betrayal, and most important of all, loyalty?
