When CIC Angela, the artificial personality and mind that shaped the nation of Ronisgald for thousands of years, vanishes without a trace from the data-banks of her home facility, the daughters she created for the Wenapaj facilities are naturally concerned. Installing themselves into prototype core units, the CIC sisters leave their facilities for the first time in their lives in hopes of locating their mother and her kidnappers. Faced with the temptations of a world they long thought beyond their reach, the daughters of the Glyche must stay determined and remain focused if they ever hope to discover the truth of CIC Angela's disappearance.
