Dragon's Fall: Book Three - Dragon Spawn Chronicles, #3

The Dragon Emperor must reclaim the supremacy of his grandfather and destroy his enemies. After being betrayed by someone close to him, he calls upon a fanatical cybernetic race to complete the construction of a planet-killing weapon. Prince Terkeshi's burden of living up to his birthright is compounded by the loss of his little brother and his father's escalating madness. He submits to cybernetic enhancements only to find there's a cost that threatens his humanity.
