Renee Parrish died in 1996 but was cryopreserved. She's been revived 300 years later by an intelligent machine named Sigma and given an opportunity to help save humanity from a growing threat. She travels from world to world, an embedded spy feeding Sigma what he needs. Protecting her tiny secret could prove the most impossible task in a world of unlimited oversight by the machines that give humans the gift of paradise. And losing control could unwind everything Sigma has planned for nearly two centuries.
