Damnation

It began with a terrible vision of the future. Compelled by her precognitive abilities, Ia must somehow save her home galaxy long after she's gone. Now Jean Johnson presents the long-awaited epic conclusion to her national bestselling military science fiction series. With their new ship claimed and new crewmembers being collected, Ia's Damned are ready and willing to re-enter the fight against the vicious, hungry forces of their Salik foes.
But shortly after they board the Damnation to return to battle, a new threat emerges. After several centuries of silence, the Greys are back, and the Alliance must now combat both a rapacious, sadistic enemy, and a terrifying, technologically superior foe. Ia has asked nothing of her crew that she herself has not been willing to give. But with two wars to bring to an end-and time running out-Ia must make and execute the most terrible choice of all.
