I really enjoyed this book along with the entire series. I could not put down as it kept me on the edge of my seat all the way through it. I could not wait to start the next book after I finished this one, it has body-snatching aliens in it. It's all around a good read.
Cassie Sullivan, the survivor of an alien invasion, must rescue her young brother from the enemy with help from a boy who may be one of them.
