Declaration trilogy

In 2140 England, where drugs enable people to live forever and children are illegal, teenaged Anna, an obedient "Surplus" training to become a house servant, discovers that her birth parents are trying to find her.

When a Pincent Pharma truck is ambushed by the Underground, revealing not the expected supply of drugs but corpses, it becomes clear that the Longevity prescription for eternal youth is failing to live up to its promises, and when the Underground is blamed for releasing a deadly virus, the truth finally comes out.
