Fractured Code - Book 4: Blood Code (Paperback) (ISBN-13: 9798262856152)

Two years after defeating an AI that tried to predict human behavior, Marcus Reeves and Sienna Cross face their ultimate challenge: a genetic conspiracy that threatens to rewrite human evolution itself.

When deaths begin following genetic patterns from ancestry testing, Marcus and Sienna uncover the Genesis Collective's terrifying plan. Using DNA profiles as targeting data, they're systematically eliminating people with "undesirable" genetics while creating genetically modified populations designed for compliance.

From the frozen research stations of Siberia to the elite genetic facilities of New Zealand, from Iceland's unwitting population experiments to the UN Security Council in Geneva, Marcus and Sienna race against a countdown that could transform humanity forever.

But the Genesis Collective has been expecting them. Dr. Evelyn Thorne, daughter of their former nemesis, has orchestrated a genetic modification program that would make behavioral control literally inescapable. The only hope lies in Emily's final gift: genetic countermeasures embedded in her DNA five years ago.

The ultimate battle for human genetic autonomy begins now.
