I read all 9 books in the series in about 3 weeks, and yes, I am an adult. Also, although I enjoy a zombie movie now and then, I am not a hardcore zombie fan, but I couldn’t put these books down. Here’s why:First of all, it is a testament to the author’s skill that he is able to write these books in the first person point of view. As I read the first few paragraphs I considered stopping right there because first person is severely limiting and is not done well nearly as often as it is attempted. But by the time I read a few more paragraphs, I was hooked. I read the nine books essentially non-stop.Second, the main character is relatable, not so much because of his personal history pre-zombie times but because of how he thinks of himself, generally speaking. He’s a guy with a few emotional scars and a few strengths, and he’s just trying to find a place in the world. Now that the world has been zombie-fied, things get a bit more dramatic than before.Third, the whole “slow burn” concept is a great twist on the whole zombie setting, one that I can’t recall being used in any other zombie story, ever.Fourth, the author’s inventiveness surfaces over and over again, in clever and surprising ways. I don’t think there was a cliché or even a slightly tired scene in any of the 9 books. I won’t give anything away here, but you’ll see what I mean when he figures out how to refuel a piece of farm equipment.Fifth, the author knows a few things about animal behavior, which he applies to the zombies. Clue: various groups of zombies exhibit radically different behaviors.Sixth, the pacing is great. Something is either happening or about to happen, and nowhere in the books does the author bore you with useless exposition.Seventh, the dialogue is done well. Different characters sound like different people, and even in quiet scenes they talk like people exhausted and stressed in a world gone wacky, not like characters in a soap opera or half-baked sitcom. Oh, and there are some rather funny lines throughout the books.Lastly, there are human interactions and emotions and growth that just happen to take place in the middle of some very wild zombie craziness. Long after you read these books, you WILL remember the main characters.So, all in all, the Slow Burn series is VERY nicely done. I’ve told a bunch of people about these books, and only when I do that do I give a book 5 stars.
