Not as good as the first book, but still an enjoyable read. The beginning and the end of the book were the best parts. While I thought the story got dragged out in the middle, it wasn't too overbearing. 
 Yancey does a good job of mixing in the characters pasts and present. At least the ones we didn't already learn about in the first book. This helps show why these characters act the way they do, and gives the story a more realistic feel. You can relate with them even though they are in a unimaginable situation. 
 This book, like the first, has multiple POV's. We still get Cassie, Ben, and Evan's thoughts along with a couple of other minor characters, but I felt this book was mainly focused around Ringer. There is a more in depth look into her struggles, how she got to where she is, and her journey from who she was to who she has become. She is, by far, my favorite character. 
 The story picks up right where the first book left off. So, the foundation that was set helps the story progress easily as we learn more about why the aliens have invaded the planet. As our group of survivors try to stay alive the truth may not be what they have come to believe. 
 I rounded up to 3.5 stars. Good continuation of the story with minor details I didn't like.
