It's been three years since Rowan and Citra disappeared; since Scythe Goddard came into power; since the Thunderhead closed itself off to everyone but Grayson Tolliver.

In this pulse-pounding conclusion to the New York Times bestselling author Neal Shusterman’s Arc of a Scythe trilogy, constitutions are tested and old friends are brought back from the dead.

Citra and Rowan have disappeared. Endura is gone. It seems like nothing stands between Scythe Goddard and absolute dominion over the world scythedom. With the silence of the Thunderhead and the reverberations of the Great Resonance still shaking the earth to its core, the question remains: Is there anyone left who can stop him?

The answer lies in the Tone, the Toll, and the Thunder.

In a world that's conquered death, will humanity finally be torn asunder by the immortal beings it created?

The Children of Men is told with P. D. James's trademark suspense, insightful characterization, and riveting storytelling. This is a story of a world with no children and no future. The human race has become infertile, and the last generation to be born is now adult. Civilization itself is crumbling as suicide and despair become commonplace.

Oxford historian Theodore Faron, apathetic toward a future without a future, spends most of his time reminiscing. Then he is approached by Julian, a bright, attractive woman who wants him to help get her an audience with his cousin, the powerful Warden of England. She and her band of unlikely revolutionaries may just awaken his desire to live... and they may also hold the key to survival for the human race.
