Aria Rose, youngest scion of one of Mystic City`s two ruling rival families, finds herself betrothed to Thomas Foster, the son of her parents' sworn enemies. The union of the two will end the generations-long political feud—and unite all those living in the Aeries, the privileged upper reaches of the city, against the banished mystics who dwell below in the Depths. And she can't conceive why her parents would have agreed to unite with the Fosters in the first place.
