These enemies are not flesh and bone. How can they fight them?

Kai, the newly-crowned queen of Miina, finds her reign threatened by a plague of natural disasters that leave death and destruction in their wake. Are the gods truly angry at the peace between the moon and sunburners, or is something more sinister to blame? Kai's throne and her very life may be forfeit unless she can appease the gods' anger and her peoples' superstitions.

Determined to find a solution, Kai and the Sunburner Prince Hiro embark on an extraordinary and dangerous journey to discover the true cause of the plagues. What they find is an ancient enemy determined to plunge their world into eternal darkness — and one desperate chance to save it. 

Sunburner, Book 2 in the Moonburner Cycle, is a young adult fantasy will appeal to fans of Sabaa Tahir, Sarah J. Maas, and Leigh Bardugo.
