Present day: Icie is a typical high school teenager—until disaster strikes and her parents send her to find shelter inside a mountain near Las Vegas.

The future: Beckett lives on The Mountain—a sacred place devoted to the Great I AM. He must soon become the leader of his people. But Beckett is forced to break one of the sacred laws, and when the Great I AM does not strike him down, Beckett finds himself starting to question his beliefs.

As Beckett investigates The Mountain's history, Icie's story is revealed—along with the terrifying truth of what lies at the heart of The Mountain.

Sara Grant's Half Lives is a dystopian chronicle of the journeys of two unlikely heroes in their race against time to save future generations.
