Kira, Samm, and Marcus fight to prevent a final war between Partials and humans in the gripping final installment in the Partials Sequence, a series that combines the thrilling action of The Hunger Games with the provocative themes of Blade Runner and The Stand.

There is no avoiding it—the war to decide the fate of both humans and Partials is at hand. Both sides hold in their possession a weapon that could destroy the other, and Kira Walker has precious little time to prevent that from happening. She has one chance to save both species and the world with them, but it will only come at great personal cost.

With humanity’s last survivors and the remaining Partials on a collision course, can one girl’s sacrifice prevent total annihilation?

• A Race Against Extinction: Humans hold a nuke and Partials hold the plague. Kira Walker is caught in the middle, with time running out to stop a war of mutual destruction.
• Genetically Engineered Soldiers: The Partials, facing a deadly expiration date at age twenty, will do anything to survive—even if it means wiping out their creators for good.
• High-Stakes Series Finale: Don’t miss the epic conclusion to the Partials Sequence, where every alliance will be tested and the fate of the world will be decided once and for all.
• A Heroine’s Sacrifice: Kira believed she held the cure for both species. Now, her one last chance to save everyone will demand a price she may not be willing to pay.
