The Sons of Sora: The Earthborn Trilogy, Book 3

The epic science fiction trilogy concludes with a thrilling novel in which the last of humanity must face its most devastating enemy in a final conflict.
 
When Noah was a young orphan, the Xalans destroyed the Earth, driving mankind across the stars. Now, he is a leader of the young enclave of Earthborn who reside on the planet Sora.
 
When the tranquility of their settlement is shattered by a shocking assassination attempt, Noah turns to his combative younger brother Erik for aid. Their journey takes them to the remnants of a dead planet, an outlaw-infested space station, and back to Sora, whose inhabitants are bracing for a final showdown with the bloodthirsty Xalans. And the danger of human extinction is greater than ever.
 
The omnipotent Archon—who controls the entire Xalan horde— has unearthed knowledge that could wipe both Sorans and humans alike from the face of existence. And the descendants of the Earthborn must uncover the secrets of the Archon and the Xalans before he burns everything they know and love to ashes.
