This richly imagined fantasy series inspired by Persian mythology and Islamic lore is filled with action, magic, and self-discovery. “A jewel of a fantasy novel that shines with adventure and sparkles with humor.” —A.F. Steadman, New York Times Bestselling author of Skandar and the Unicorn Thief 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.
