I've been going threw TWD withdrawls so I've been googleing the show and seeing what comes up. I found a really good wiki for the comic books. I don't read comics as they don't translate into a story very well for me. So I've been enjoying the synopsis on this site. I've read from the beginning to the last issue and I don't think I've really spoiled anything for myself. The comics are very different then the show.
Issue 1 - Walking Dead Wiki
Click to see Spoiler:One character that is going to be introduced in the next half of season 4 is Abraham. I cannot wait to see if he's like the comic book version or not.
