[MP3-CD audiobook format in Vinyl case. *NOTE: The MP3-CD format requires a compatible audio CD player.][Read by Charles Carroll]Carl Sims, a young virologist, has discovered a plot hatched by a group of international scientists to cull, in a matter of weeks, two-thirds of the world's population--some 4.5 billion people--by releasing a deadly virus. Their goal is to reduce Earth's population from an unsustainable seven billion to two billion. Should he try to stop the conspiracy or join it? It's horrific, but what if this culling could prevent the extinction of some 40 percent of the planet's flora and fauna? Or if it was the only way to prevent an even larger human die-off? Or if it represented the only hope for humanity's survival? These are the questions at the heart of this thriller, for these viruses do, in fact, exist.
