Calla Cress took down the world's most dangerous man. She made one mistake. She let him live.

A billionaire behind bars, once the secret service's most brilliant code breaker, is luring the world's smartest minds into his prison cell. They leave in a coma and seconds later a lethal hack snakes through one government system after another.
Meanwhile, Calla Cress, museum curator turned undercover cyber-security agent, faces the biggest dilemma of her life. She's harboring a dangerous secret buried in the deepest vaults of technology history.

In a few hours, she'll have to make a decision that will change her life forever. After an explosion rocks her hideout in Colorado, Calla wakes up halfway across the world at the whim of a powerful, unidentified organization demanding she produces the whereabouts of a missing MI6 agent who can disarm the billionaire's hacks.

With only a handful of clues left in a mysterious sixteenth-century anagram encrypted with a sequence of codes, Calla, NSA security advisor, Nash Shields and tech entrepreneur Jack Kleve are thrust in a dangerous race across the globe. With each haunting revelation, they soon realize the key to disarming the hacks comes at an astonishing price.
