Book excerpt: These essays show just why these mutants have such astonishing endurance and staying power. Contributors trace the series' evolution, challenge its metaphors and draw from its truths about human nature and society. From real mutant subcultures in our world to the reality of racism and heterosexism that are not so different from that of the X-Men, The Unauthorized X-Men takes on the intersection between fiction and truth in a volume perfect the long-time comic readers, cartoon fans and movie goers alike.
