Roselle faces a mind-reeling showdown with the deep state agent controlling her psyche in the conclusion to the Wall Street Journal bestselling Secondborn series. Roselle St. Sismode is many things: victim of a conspiracy, unwilling host of an ever-evolving mind algorithm, spy for a rebel army, and heir to the Fate of Swords. As a warrior, she’s also the anticipated main event at the Secondborn Trials. When the opening ceremonies erupt in chaos, Roselle is abducted by a sadistic agent with a diabolical plan: transform Roselle into a mind-controlled assassin to topple society. But a rogue scientist has implanted Roselle with a genius technology that is far more powerful. It renders her untouchable. Faster. Stronger. And maybe immortal.
