This final novel in the acclaimed Seventh Flag Trilogy thrusts readers thirty years into the future-a dystopic reality of regional fiefdoms, marauding scavengers, and the quest for ultimate power: the Algorithms of everything, which have been secretly pilfered from an undersea Internet cable, stored on hard drives, and implanted in the last surviving blue whale. Ademar Zarkan-the iconic and unlikely heroine of the American West, now a seventy-year-old woman-leads the Free People of West Texas in an alliance with Native Americans and the indigenous people of northern Mexico to retrieve the hard drives and to rescue her clairvoyant granddaughter from the radicalized Sisterhood and its merciless leader, Mother. But they aren't the only ones in pursuit of the Algorithms. Haunting and prophetic, Algorithms is a story of violent extremism, resilience, family, and, above all, the interconnectedness of humankind and the natural world.
