Sequel to 'City of Masks' and 'City of Stars', the narrative moves to the Talian equivalent of the 'City of Florence', where beauty and danger walk - as ever - hand in hand. The focus this time is on the new Stravagante, Sky, whose talisman is an ornate and delicate blue glass bottle. Sky is propelled right into the midst of a deadly feud between the di Chimici and Nucci families, who think nothing of sliding a knife between a man's ribs for revenge. The drama with a kind of magic, continues the stories of Luciano, Arianna, Rodolfo, Falco and Georgia.
