The reborn empire, book 1 : We Ride the Storm
Devin Madson2018

In the midst of a burgeoning war, a warrior, an assassin, and a princess chase their own ambitions no matter the cost in Devin Madson's propulsive epic fantasy.
War built the Kisian Empire. War will tear it down.
Seventeen years after rebels stormed the streets, factions divide Kisia. Only the firm hand of the god-emperor holds the empire together. But when a shocking betrayal destroys a tense alliance with neighboring Chiltae, all that has been won comes crashing down.
In Kisia, Princess Miko Ts'ai is a prisoner in her own castle. She dreams of claiming her empire, but the path to power could rip it, and her family, asunder.
In Chiltae, assassin Cassandra Marius is plagued by the voices of the dead. Desperate, she accepts a contract that promises to reward her with a cure if she helps an empire fall.
And on the border between nations, Captain Rah e'Torin and his warriors are exiles forced to fight in a foreign war or die.
As an empire dies, three warriors will rise. They will have to ride the storm or drown in its blood.
