C. A. Higgins’s acclaimed novel Lightless fused suspenseful storytelling, high-caliber scientific speculation, and richly developed characters into a stunning science fiction epic. Now the dazzling Supernova heightens the thrills and deepens the haunting exploration of technology and humanity—and the consequences that await when the two intersect.

Once Ananke was an experimental military spacecraft. But a rogue computer virus transformed it—her—into something much more: a fully sentient artificial intelligence, with all the power of a god—and all the unstable emotions of a teenager.

Althea, the ship’s engineer and the last living human aboard, nearly gave her life to save Ananke from dangerous saboteurs, forging a bond as powerful as that between mother and daughter. Now she devotes herself completely to Ananke’s care. But teaching a thinking, feeling machine—perhaps the most dangerous force in the galaxy—to be human proves a monumental challenge. When Ananke decides to seek out Matthew Gale, the terrorist she regards as her father, Althea learns that some bonds are stronger than mortal minds can understand—or control.

Drawn back toward Earth by the quest, Althea and Ananke will find themselves in the thick of a violent revolution led by Matthew’s sister, the charismatic leader Constance, who will stop at nothing to bring down a tyrannical surveillance state. As the currents of past decisions and present desires come into stark collision, a new and fiery future is about to be born.
