Void's Vengeance. Death's Disciple, #4

Former captain Yala Palathar is once again in exile, while a tyrant sits upon the throne of Laria. The armies of the dead stalk the lands, while across the country, the orders of Disciples are falling, one by one. Amid the chaos, Yala is offered an opportunity to return to the battlefield as a soldier of the highest rank. Accepting might be her only chance to get close to her enemy, but at the cost of being drawn deeper into the god of death's domain. Niema, too, faces a raging battle in her heart, between the promises she swore to the god of life and the knowledge that the god of death has marked her, too. As the gods of life and death prepare to wage all-out war, Yala and Niema face choices that will shape the future of the nation and the world at large.
Either they will bring an end to a conflict years in the making, or else watch everything they hold dear fall into the ruinous void.
