Aliens have invaded Earth. They are not just among us, they are in us! Well, just some of us. The vast majority of humans that aren’t hosting a little alien shadow are pretty much killed off before the book begins. When the army comes to the survivors’ rescue and they leave with little Sammy, big sister Cassie is determined to find him and get him back. When the aliens look like humans, it is hard to tell who to trust. Action-packed and stocked with the self-sacrificing characters of Cassie, Ben, and Evan, this will be one popular book among teens. There is a bit of foul language, so if that is a concern, perhaps older teens.  If an alien was intent on killing me, I doubt I would say, “Golly jeepers!” Highly recommend.
