BlyssPluss pill conceals an extinction plague
Crake, a prodigy at a biotech corporation, markets BlyssPluss, a pill promising boosted libido, disease protection and prolonged youth, and secretly loads it with a timed hemorrhagic virus (JUVE) that kills almost all of humanity within weeks of global release. He has already built the Crakers, an engineered replacement species, in a sealed dome called Paradice. He pre-vaccinates his friend Jimmy so someone survives to lead them out, then cuts Oryx's throat in front of Jimmy, who shoots him. Jimmy becomes 'Snowman,' the apparent last human, shepherding the Crakers.
