USA Today bestselling authors Harris and Gentry deliver a gripping medical thriller ripped from today's headlines.

There are diseases hidden in the ice and they are waking up.

Virus hunter Aiden Ballinger believes the source of the lethal outbreak that decimated a remote Tibetan village came from disturbing the permafrost. Desperate to rebury it before it buries the world, Aiden enlists Rachel Allen, a beautiful epidemiologist. But while Aiden and Rachel pursue the cure—and their feelings for each other—someone is hunting them. Whoever wants them dead will not stop until they are silenced.
