On a sparsely populated Mars remade by E-power and telepathic science, Lynne Marcein is already a rarity before her pregnancy makes her a planetary sensation: the only visibly pregnant woman on Mars, carrying a child in a world where birth should be nearly impossible. Her husband Rolf is stranded on Earth by political delays, leaving Lynne to endure isolation, scrutiny, and the weight of a future that could change Mars forever. Inspired by Rana Willis, the first woman to bear a child on Mars through fierce mental discipline, Lynne has followed the same path—and now Dr. Smetana watches her case with astonishment. But Lynne's personal miracle is overtaken by a darker frontier crisis. At Patagonia Station, cattle begin behaving with eerie intelligence, then break into wild, coordinated frenzy. With her telepathic twin Revere, Joanna Wheatley, and station director Martin Juarez, Lynne discovers that the herd is being possessed by "zombies," electrophagic Martian entities that feed on electrical power and seem to exploit E-power storms. When a charging herd destroys her vehicle, Lynne turns her psychic gift against the invaders, reaching the animals' buried instincts and forcing a stampede. Yet the threat is only partly understood, and with communications blocked, Mars's fragile future hangs on a battle against an old enemy in a terrifying new form.
