The official description of the title is as follows:
"From one of the most acclaimed and oracular writers in the world of comics comes a thrilling and provocative exploration of humankind’s great modern myth: the superhero.
"For Grant Morrison, possibly the greatest of contemporary superhero storytellers, these heroes are not simply characters but powerful archetypes whose ongoing, decades-spanning story arcs reflect and predict the course of human existence: Through them, we tell the story of ourselves. In this exhilarating book, Morrison draws on history, art, mythology, and his own astonishing journeys through this alternate universe to provide the first true chronicle of the superhero-why they matter, why they will always be with us, and what they tell us about who we are."
