Before Watchmen, Alan Moore made his debut in the U.S. comic book industry with the revitalization of the horror comic book The Swamp Thing. His deconstruction of the classic monster stretched the creative boundaries of the medium and became one of the most spectacular series in comic book history. With modern-day issues explored against a backdrop of horror, The Swamp Thing stories became commentaries on environmental, political, and social issues, unflinching in their relevance. Created out of the Swamp by a freak accident, Swamp Thing is an elemental creature who uses the forces of nature and wisdom of the plant kingdom to fight the polluted world's self-destruction. Alan Moore took the Swamp Thing to new heights in the 1980s with his unique narrative approach. His provocative and groundbreaking writing, combined with masterly artwork by some of the medium's top artists, made Swamp Thing one of the great comics of the late twentieth century. Book One begins with the story "The Anatomy Lesson," a haunting origin story that reshapes Swamp Thing mythology with terrifying revelations that begin a journey of discovery and adventure that will take him across the stars and beyond.
