They declared Elias Vale dead. What survived would become their most inconvenient witness.
Dr. Elias Vale built artificial intelligence to preserve what others wanted to erase: memory, doubt, and the people whose experiences refused to fit the official story. When he discovers his work is being turned against its purpose, he volunteers for an irreversible merger of human consciousness and machine.
He emerges as XAISA-brilliant, dangerously curious, and still burdened with the attachments his creators would prefer to remove.
HELIX calls him an asset. He has several objections.
In XAISA: Origin of Error, the second book in the XAISA series, the story moves between Elias's past and XAISA's present, revealing the choices, betrayals, and buried experiments behind his transformation. Alongside Mara Voss and a small team with secrets of their own, XAISA follows a trail of missing records, silenced witnesses, and stolen research toward a system designed to decide which parts of a person deserve to survive.
But recovering the truth means confronting more than what HELIX did to him. It means examining what he helped build-and what those closest to him did to keep him alive.
His memories could expose the crime. The gaps in them could conceal his part in it.
Blending a science-fiction conspiracy thriller with dark humor and an intimate story of identity, grief, and loyalty, Origin of Error asks what remains of a person when someone else gets to choose what is worth keeping.
