Venice is a carnival of opposites, and Liona Carvatti thinks she understands it all: canal and palace, magician and merchant, plague and pantomime. As a patrician's daughter, Liona enjoys the sparkling life of a noble family--although she would prefer to be tending to her flowers than practicing violin or standing around in a ball gown. But what Liona fails to realize is that Venice is a city of stone in a world of water. And ruling the dark waters are the Seleni--ageless, cold, and calculating. When she loses everything she relies on, Liona must set a new course that will shake the foundations of Venice itself.
