The Witch of Lurago by L.H. Leonard

Resistance rumbles. Rebellion erupts. War sweeps across the continents as Rhynn and Este fight to free their people. Seth leads an army of unlikely allies into battle. As he chases the Butcher of Bloody Bend toward Jorendon, his darkest secret follows him, daring him to face a truth that could cost him all he loves.

Malatchee Mico confronts Tobias about betraying his trust. Determined to free his sister's son from captivity, Malatchee gives Tobias one chance to restore the balance or else leave Tallu forever. They will go to war in Philippeon together and drive the Laradian snakes into the sea. But with war comes sacrifice. Who will pay the price?

Mouse gets a name and meets her Reader. Dara struggles with the horror of his crime. Deighton faces an accounting for his deceit. Puppeteers incite mass panic, and the kazera venture out of hiding.

The Rootstock Saga characters you know so well are in a race against time. The water is rising, and the Watchers are coming for the harvest. Even as war distracts them from the paths the Patterns demand they follow, when the Witch of Lurago awakens a mindgift like no other, the chalyns and their destinies begin to converge.
