Seventeen-year-old Eira Thorne wakes inside a cryo-pod buried deep beneath the ice—disoriented, gasping for air, and utterly alone. She has no memory of who she is, why she was frozen, or what happened to the world while she slept. Above the ice, the story is legend: an asteroid struck Earth, triggering the Frost Era, a cataclysmic new Ice Age. Out of the disaster rose fortress cities carved into glaciers, scavenger clans roaming the wastelands, and the Dominion, a ruthless force that controls the last scraps of technology. And everyone agrees on one thing: the cryo sleepers should never have woken.

Taken in by rebels who believe she holds the key to uncovering the truth behind the Frost Era, Eira must survive in a world that doesn’t trust her. But when the Dominion discovers she’s awake, she becomes their target, because they know exactly why she was frozen, even if she doesn’t.

With a dangerous rogue named Cael at her side, Eira must uncover the truth buried in the ice before the Dominion silences her forever. Because the asteroid wasn’t the end.

It was only the beginning.
