Ruth’s tireless research into the disease that killed her young daughter had an unexpected outcome: the discovery of a vaccine against old age. Just one jab a year reverses your biological clock, guaranteeing a long, healthy life. But Ruth’s cure was hijacked by her colleague, Erik Grundleger, who hungers for immortality, and the SuperJuve – a premium upgrade – was created, driving human lifespan to a new high. The wealthy elite who take it are dubbed Supers, and the population begins to skyrocket. Then, a perilous side-effect of the SuperJuve emerges, with catastrophic consequences. As the planet is threatened, the population rebels, and laws are passed to restore order: life ends at 120. Supers are tracked down by Omnicide investigators and executed. Meanwhile, Grundleger has been working on something even more radical, and has a deadly surprise in store.
