Promises of War: The Assembly of Thirteen

By Omayra Vélez

The Empire is on the brink. Two brothers wage war for the throne-but neither will rule.

In the fractured Empire of Quetza, civil war erupts as the Falesto brothers marshal their forces. Emperor Klastos, driven by obsession and darkness, demands total loyalty. He clings to power by all means possible. Across the five kingdoms, alliances crumble, monarchs choose sides-or are crushed for refusing.

Ancient forces stir. Destroyers, demons, and dead walkers now walk the battlefield beside men, each side willing to unleash horror to win. In the West, Queen Herena try not to bend to pressure. In the South, King Bartolome of Karkat resists the Emperor's call, guarding his elite Chanta Warriors from being used as pawns in a war of madness.

But the civil war is only the surface.

All the Companions and Gifted are alive, and with them, a more profound truth: if they choose a new Emperor, the new leader will need an Army. Whoever wins the throne will have to fight whichever Falesto brother who may win the civil War. For the Assembly will choose the true Emperor-and that choice will reshape the realm.

Amid the chaos, Corrysande, bound by blood to her father and to the Emperor by a hex, is sent to spy on Bartolome by Klastos. She walks a perilous path-haunted by a curse from her brother Gallo that threatens her mind and soul.

Far away, June and her companions fight to reach Athany Castle, where the last secrets of the Thirteen await. But a ruthless army and a powerful mage stand in their way. Kara and Karl must risk everything, or the Assembly will shatter before it can rise. On the other hand, Callo runs to the Castle as the Green Companion.

War is coming. Magic is rising. And prophecy is running out of time.
