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.
