Farrah sees her father just one day every year—her birthday. But this year, her wish to bring them closer goes wildly awry when Farrah discovers she is a half-jinn...and her father is one of the seven great jinn kings. Her wish traps her father inside a legendary ring, and the other six jinn kings will follow unless Farrah can rectify her mistake.

Pursued by menacing shadow jinn, Farrah’s quest takes her to a floating mountain range. Joined by Idris, the jinn boy whom she inadvertently freed from the ring, and her newly discovered half-brother, Yaseen, Farrah must find a way to navigate the mysteries and dangers of her new world in order to save her father and face the most devious jinn lord of all.
