Teenager Cassie Sullivan is a survivor of an alien invasion. She must rescue her young brother from the enemy with help from a boy who may be one of them. 

I really enjoyed this book. Although, I think that it may be a little too scary for some 6th graders. I liked that the book ended without a cliffhanger and that you do not have to read the next book in the trilogy. I would recommend this book to students and adults who like science fiction.
