London, 2042. Ofelia Stykes can’t forgive herself. Having lost her older sibling to the snatchers, the nearly sixteen-year-old scavenger vows to protect what’s left of her family from the lethal pandemic that toppled society. But when her little sister is captured as they dig through trash for treasure, the brave teen surrenders herself in exchange for the child’s freedom.

Locked in a research facility and subjected to tests, the desperate young woman shrewdly searches for an opportunity to escape with the rumored cure. But with the morally bankrupt chief virologist believing Ofelia’s DNA could save all of humanity, the extraordinary teen fears time is running out before she’s the next to die in a horrific experiment.

Can she uncover the truth and prevent an earthshaking disaster?
