What this book is about
A Robin Cook medical thriller (1997) with science fiction elements, in which a new kind of virus — seemingly of extraterrestrial origin — begins spreading through the human population. Those infected undergo a personality transformation, becoming docile and compliant. Dr. Sheila Miller must find the truth about the mysterious black discs appearing across America. Unusual departure from Cook's typical medical procedural.
