A half-human, half-jinn girl tries to save both her worlds from destruction in the second book of this richly imagined, action-packed fantasy series inspired by Persian mythology and Islamic lore.

On her twelfth birthday, Farrah Noorzad found out her father was one of the seven jinn kings. Now, one epic quest and a whole lot of adventure later, she hasn't seen her father since she saved him from a cursed ring, and her place in the jinn world as a forbidden half-human is still more up in the air than a flying cloud. Not to mention that in the human world, she's moved away from her best friend Arzu because her mother wanted them to have a fresh start.

So when she is summoned by the kings after months with no word from her father or her half-brother, Yaseen, she jumps at the chance to return to the floating jinn city and attend the glittering, magical Al Qalam Academy for the Exceptional while the kings make their final judgement. Farrah just has to prove she belongs at her father's side, and maybe even help Idris finally uncover his missing memories along the way.

But all the while the fire jinn Azar continues to whisper in her ear, sowing doubt and fear about her true place and her true powers. And when the City of Jewels is threatened, fate steps in once again, with a prophecy that claims Farrah might be the one to save the jinn world...or destory it.
