Okay, first of all, it's so awesome that you love Metallica. Second of all, it's so awesome that you think Seth is adorable! And third of all, it's so awesome how awesome this story seems after reading just the first freaking chapter!
At first I was very hesitant at reading this because, well - it sounded dumb from the whole zombie thing. But you're a great writer so you pull it off! I love it, and I can't wait for more chapters.
