Watchmen

In an alternate 1985, superheroes have existed for more than 30 years and have endured the gamut of public opinion--from acceptance to polite disdain to outright hostility. Now someone is killing the second generation of superheroes, and, as the threat of nuclear holocaust looms over a dystopic world, the killer must be found before it's too late. Originally published in 12 separate comic books, which are collected here along with some additional material, this book is perhaps the seminal graphic novel.
