Legion Ascendant

Silas Vane bound two million souls to his will and broke an empire of the dead to do it. Six months later, the Matrix fused to his nervous system is still healing - and the void has noticed him anyway. The Voidborne are coming, an armada of Harvesters who consume souls the way other empires consume territory, and they've marked Silas's realm as their next meal. To fight back, he'll have to master a weapon terrible enough to match them: the Soul-Lance, a device that trades a willing soul for the death of a god.
Every shot fired is a name Silas will have to remember. Every victory costs someone he loves. With his ghostly second-in-command Thalia at his side and a council that isn't sure he can be trusted with the power he carries, Silas must decide how much of himself - and his people - he's willing to spend to survive what's coming. Because somewhere in the deep void, the First Hunger has felt its child die, and it is not something that forgives.
