Captain America: The First Avenger is a junior novelization of the film of the same name.
All Steve Rogers ever wanted to do was join the U.S. Army and fight for his country. But he was too sick and frail to pass the required physical. His patriotic dreams were shattered...until a secret branch of the military offered him a once-in-a-lifetime opportunity: Steve would be the test subject in an experiment that would transform him from a weak, unhealthy civilian into a mighty Super-Soldier! Now known as Captain America, Steve is thrown onto the battlefields of Europe, where he must embark on a dangerous mission to stop the evil Red Skull--and his diabolical HYDRA organization--from destroying the entire world!
