Jacqui still remembers what it was like before the honeybee virus destroyed her world. Before children turned into beasts and men desperate for power became raiders. Before she had to disguise herself as a boy. And before her brother Dean left and never came back.

"Jack" asks Fiona and Jonah Tarsis to help find Dean, and they quickly set out-along with Fiona's boyfriend, Bowen-in search of their loved ones. But Jacqui soon discovers that they've kept a dangerous secret from her: they have the cure. With their survival hanging in the balance, Jacqui and her friends must restore their families, preserve the cure, and fight for the chance to rebuild their shattered world.
