This book was really good and it definitely got me interested in reading the rest of the series. Really I would give it a 4.5 out of 5 stars. 
 The concept is interesting, all adults and teenagers over the age of 14 just vanished from this California town one morning and all the kids of the town were left to figure out what is going on. Throw in barrier completely surrounding the town, kids with strange new powers developing and creepy mutating animals and you have a very interesting book to say the least. 
 I liked how they tried to re-build their own little community and some of the older kids took "jobs" running different areas. It made it seem realistic that they had to set up a daycare for all the babies that obviously could not look after themselves. I liked that the author thought about those details. 
 I liked the characters in the book, and I disliked the bad one, but my problem is that I didn't love anyone. That is really my only complaint. Sam, the main character that all of the kids look to as their leader, was nice and smart enough but I felt like he was missing something for me. Maybe he will show some character growth in the next book. 
 But the plot is really, really good. I am intrigued. I want to figure out what is causing the "poof" of people 15 and above. and I want to figure out where all the people go after they Poof. I hope we dont have to wait till the last book to get some answers.
