When I first got my hands on Warm Bodies by Isaac Marion I was thrilled. The story seemed original with its zombie-plot, but my idea of this novel changed quite a bit after a while. I did enjoy the story and I probably will if I ever decide to pick it up again, but the story is not original at all. Instead it echoes Shakespeare.
Warm Bodies is more like a post-apocalyptic version of Romeo and Juliet where Romeo kills Paris and marries Juliet. In Isaac Marion's version R kills Perry who is trying to protect his girlfriend Julie. When I first discovered this I was stunned. Shakespeare probably had some inspiration from Tristan and Isolde but at least he was smart enough to make the love story is own.
