An empire is about to fall, and only rebels, traitors and a strange girl can save it. After the assassination of the emperor, the Empire of the Peaks has divided into three: those loyal to the new Emperor, Mizcarnon; those following the usurper Lanthia; and the rebels who see a chance to create the empire they've dreamed of. Caught amidst the intrigue, Zornan, Calla and their friends are focused on rescuing their daughters. But as they search for Windsa and Caldry, they find a greater threat to the empire and their freedom: the conquering giant, Nansart. Jayzca already knew of Nansart and his conquering minions. Isolated in Mizcarnon's mountain capital an ocean away from her beleaguered homeland, Jayzca must decide between being an observer, a spy or, perhaps, a savior. LIGHT OF MOONS (THE EMPIRE OF THE PEAKS BOOK 4) continues the epic adventure of magic, family and destiny.
