The complete Patternist series—the acclaimed science fiction epic of a world transformed by a secret race of telepaths and their devastating rise to power. In the late seventeenth century, two immortals meet in an African forest. Anyanwu is a healer, a three-hundred-year-old woman who uses her wisdom to help those around her.

Over the next three centuries, Doro mounts a colossal selective breeding project, attempting to create a master race of telepaths.
