The Cassandrian infestation has spread to the research planet. With additional troops being flown to the system, Med Core has sent Director Sim to personally oversee the project. It falls on Light Seeker to determine the link between the Cassandrians and the third-contact species, while keeping everyone alive in the process. That isn’t the only concern. Buried in the extracted portion of her memories are details that might shed light on the nature of the alien species and the true outcome of her forbidden mission. Whatever it was, it changed the fate of everyone associated with it, Light Seeker included.
