Welcome to books that I had a hard time putting down. Also? Aliens. It was gripping, there was character development, the plot sped along nicely, and oh, I'll just be sitting over here waiting for the next book. Yes, there are aliens. Like "make noise and end up as a tasty snack" aliens. Loved it. 
 Full review closer to In the After's publication date. I had a feeling I was going to enjoy it and I was definitely correct in that assumption.
