Scarcely a year after the events of Cyador's Heirs , Lerial uses his mastery of Order and Chaos, the competing natural forces that shape his world and define the magic that exists within it, to utterly destroy an Afritan military force crossing into Cigoerne. Five years later, Lerial, now an overcaptain and a field commander of Cigoerne's Mirror Lancers, must lead three companies of troops into Afrit on a mission of mutual interest: neighboring Heldya is threatening to invade Afrit, and if that nation falls, Cigoerne is certain to be next. The mission is both delicate and dangerous; Lerial's value in the effort to repel Heldya is undeniable, but his troubled history against Afrit may reopen old wounds that will never truly heal.
