Marvel Captain America

Fresh from a covert mission, Captain America receives a message from Maria Hill written in a mysterious code that, once deciphered, enlists Cap to protect Katherine, a brilliant young computer scientist who has written a program that could revolutionize the way the internet works—for better or for worse. Uncertain who can be trusted, Captain America takes Katherine underground, going into hiding and eluding everyone from the country's top agencies to the world's most nefarious criminals. He'll go to any length to keep Katherine safe and ensure her program stays out of the wrong hands—even if it means going up against the country he has sworn to protect. Still only just grasping the technological advances of the era he has woken up in, one of Earth's mightiest heroes must now fight a battle over something he barely understands in order to protect a concept he knows all to well: freedom.
