Meet a 16-year-old superhuman: Agent Six of Hearts. He's the strongest, most effective agent in the Deck, a team of special agents fighting to uphold justice in a completely corrupt world. Six would be invincible if not for a deadly secret. He is the product of an illegal experiment by the Lab - a ruthless division of the corporation that controls his world. When the Deck begins to investigate the Lab, Six walks a tightrope between his two worlds, trying to keep his origin a secret.

But then he meets Kyntak, a boy whose past equals his own. As Six's life spirals out of control, he must face his most dangerous, thrilling mission yet.
