JAMES LOVEGROVE: The original Doctor Strange stories are episodic, and my job with this novel has been to turn them into a single, cohesive prose narrative. It was a joy and a privilege to be given this opportunity, and I relished it. How did it feel to adapt Stan Lee and Steve Ditko's work? I wanted to treat their work with the respect and reverence it deserves, but also give it a refresh and bring it up to date.
