This book is much darker than the show and should probably have all sorts of trigger warnings. The grammar has serious issues, even outside of zombies a lot of things are a big stretch, there's a definite waft of misogyny sweeping throughout (although less than in the show, honestly. Andrea and Michonne are awesome here.), a bit of racism (not as much as the show)...honestly, I probably shouldn't like this book/series so damned much.
But I do.
I'm not sure why, really. It's compelling. Yeah, a lot of stuff gets dark and nasty, but, very sadly, that's likely the most realistic aspect of this milieu. People are dicks, and they are dangerous. The artwork is pretty good, though I do wish they made the full panels color.
It's not for everyone. It's not even for everyone who likes the show. But if you're in a good place for a dark, interesting, and easy read, this is one.
