Cory and I both have raved about The Walking Dead. The Walking Dead Compendium Volume 1 collects the first forty-eight issues, which focus on human beings trying to survive in a world taken over by flesh-eating zombies.
The only downside to this 1088-page zombie-apocalypse graphic novel is that the book literally weighs five pounds. They need to make a Kindle version of it.
Despite the burdensome weight, I couldn't help opening it to re-read the series from the beginning. My high opinion of it hasn't diminished since the first time I read it — this is a hell of a great comic book.
