stravaganza city of masks

City Of Masks is about a boy named Lucien who is surviving cancer in England. He just stopped doing chemo therapy, and can't talk so his dad buys him a book to write his words in. When Lucien falls asleep with the book in his pocket he wakes up in a city made of silver. His hair has grown back and he feels healthy, but a boy come up to him and hides him, telling him that he is in Bellezza, and only Bellezzans can be there on that day. The boy turns out to be a girl who wants to try out for a school that only boys can enter, her name is Arianna. They go to the auditions and Lucien gets picked, leaving Arianna furious at Lucien and in danger for her life. Lucien turns out to be a stravegante (someone who can travel through dimensions using an object from the dimension they were not born in), and becomes the assistant of Rofoldo, another stravagante who is the close friend/lover of the duchessa (queen of Belleza). Arianna forgives Lucien, and turns out to be the duchessa's daughter, making her the next duchessa. Lucien looses the book when in Belleza though, and the Lucien in our world dies.
