I will admit. This was my fist alien invasion book, so I don't have anything to grade this against. I was very impressed. It had a nice pace. I never got bored with it. In fact, a lot of times I didn't want to put it down. The story line was very good, and easy to keep up with. The characters were well thought out and believable. At times you can see things coming before they actually happen, but it didn't hurt my outlook on the story. It was more like I was anticipating it to see if my assumption would be right. Anyway, great read! Hoping the next two books are just as good.
