The Secret Empire (Captain America Epic Collection, Volume 5)

Steve Englehart and Sal Buscema take Captain America and the Falcon on a journey through the madness and machinations of Doctor Faustus! The mind-bending Doctor has captured Sharon Carter, A.K.A. Agent 13 - but little does Cap know that Faustus also has Peggy Carter, Cap's long-lost love from World War II! Then, Nick Fury and S.H.I.E.L.D. conscript Cap into the fight against the Yellow Claw. But the real menace to mankind is subtly concealed: A Secret Empire moves behind the face of American power! Their goal is to frame and discredit Captain America, replacing him with their own "patriotic" icon. And only the combined efforts of Cap, the Falcon, S.H.I.E.L.D. and the X-Men can hope to topple them! It's a shocking saga that defined Captain America for the '70s!
