Goodreads Summary:A sickness has afflicted everyone over the age of 16; anyone who is a "grown-up" has become a decomposing, brainless creature that survives by feeding on children. The children and teens have barricaded themselves in fortified buildings, fighting off attacks from the grown-ups who travel in packs, like hungry dogs. Before long, the young survivors are promised a safe haven in Buckingham Palace and make their way to it, crossing London on a perilous journey that will test them in harrowing ways. But their fight to stay alive is far from over—the threat from within is as real as the one on the outside.Review:There are exactly 665 ratings of this book on Goodreads. Only 665. It's a travesty. Why? This has to change. I'm going to do my part to help it along. There's an influx of dystopian and zombie novels as of late. It's the latest craze apparently. So why is the best one I have read yet not more popular? I don't get it! I'm not saying the others aren't good, but The Enemy is like a non-stop roller coaster ride. And there isn't a single lull in the action. It's full of gore, heart-stopping moments, and places where I forgot to breathe I was so scared. And the best part? There's a second book! Look I'll admit that the idea of "grown-up" zombies feeding on children is a slightly amateurish idea. But I promise you that the minute you start reading, you will completely forget this. Some of my reviews get technical where I talk about story elements, pacing, characterizations, and the like, but I don't really want to do that with this review. It's not necessary. Charlie can write a killer action story and that's all you need to know. He's not afraid to do what he needs to do to keep the story moving along, even if things have to get really scary. I guess I would call this a young adult novel. But it's very violent. You know how the Hunger Games is violent? I think this is even worse than that. I found myself cringing in a lot of places. But it didn't really bother me. I really, really loved this book. Zombies are like my favorite thing to read about lately. I don't really see that changing anytime soon. They scare the bejeezus out of me. So do me a favor. If you love dystopians, if you love reading about zombies, you need to add this one to your TBR list. Then you need to click on that list and move this book to the top. After you read it, come back here and let me know what you thought. I can't think of a single person that I wouldn't recommend this book to.
