"To beat his dark half, will Strange have to become something even worse? Many years ago, Doctor Strange fought in a five-thousand-year battle called the War of the Seven Spheres. But how did that war create the mysterious threat that plagues the Master of the Mystic Arts today? Stephen Strange is a doctor who has sworn to do no harm. But there's another, darker side to him - and it's his duty to win at any cost. Can Stephen best his mirror image, trained through thousands of years of mystic combat? General Strange has millennia of fierce and ruthless experience over the Sorcerer Supreme - but Doctor Strange has friends. Can they protect the Earth and all of magic itself?"--Provided by publisher.
