New from Houghton Mifflin Harcourt: Upon a Burning Throne by Ashok K. Banker.
About the book, from the publisher:
In a world where demigods and demons walk among mortals, the Emperor of the vast Burnt Empire has died, leaving a turbulent realm without an emperor. Two young princes, Adri and Shvate, are in line to rule, but birthright does not guarantee inheritance: For any successor must sit upon the legendary Burning Throne and pass The Test of Fire. Imbued with dark sorceries, the throne is a crucible—one that incinerates the unworthy.Visit Ashok K. Banker's website.
Adri and Shvate pass The Test and are declared heirs to the empire… but there is another with a claim to power, another who also survives: a girl from an outlying kingdom. When this girl, whose father is the powerful demonlord Jarsun, is denied her claim by the interim leaders, Jarsun declares war, vowing to tear the Burnt Empire apart—leaving the young princes Adri and Shvate to rule a shattered realm embroiled in rebellion and chaos....
Welcome to the Burnt Empire Saga.
