"We will not let Earth become a tomb, a mass grave spinning through space. We will exhume ourselves. We will fight the curse and break it. We will cry and bleed and lust and love, and we will cure death. We will be the cure. Because we want it."
To be honest, I only read the book because I saw the movie. And it may be rare, but I like both equally and for different reasons. The book is a little different from the movie and more detailed, but the movie didn't spoil this either. 'R' is more lovable in the novel because you get to 'hear' much more of his struggle to stay alive.
A different take a the zombie theme, and it paid off well.
