The first-ever full reckoning with Marvel Comics' interconnected, half-million-page story, a revelatory guide to the "epic of epics"--and to the past 60 years of American culture--from a beloved authority on the subject who read all 27,000+ Marvel superhero comics and lived to tell the tale. The superhero comic books that Marvel Comics has published since 1961 are, Douglas Wolk notes, the longest continuous, self-contained work of fiction ever created: over half a million pages to date, and growing. The Marvel story is a gigantic mountain, smack in the middle of contemporary culture. Thousands of writers and artists have contributed to it. Every schoolchild recognizes its protagonists: Spider-Man, the Avengers, the X-Men. 18 of the 100 highest-grossing movies of all time are directly based on parts of it. And not even the people telling the story have read the whole thing--nobody's supposed to. So, of course, that's what Wolk did: he read all 27,000 comics that make up the Marvel universe thus far, from Alpha Flight to Omega the Unknown. And then he made sense of it: seeing into the ever-expanding story, in its parts and as a coherent whole, and seeing through it, as a prism through which to view the landscape of American culture.
