3/5 Stars. This was my husband's favorite book series as a kid so I wanted to read them all. I could not review all of them until I finished the series.

Description: New MC again: Jon (Jonathan, Jonny) lives in an enclave (get ready, there's a lot of new lingo) which is the safe towns mentioned in earlier books. He lives nearby his family, but they live outside that enclave and are considered 'grubs'. The 'clavers' look at Jon as a 'slip', because his family was not rich enough to get in but he had a pass to enter the town. Jon is on the soccer team that proves the enclaves strength and if he slips up (haha) then he's out of there. However, when a girl comes to town, he starts to question his entire life (again)

The good:
- I was still very emotionally invested in the series, this was still an emotional book, which I enjoyed
- This book introduces us to more of the world than in the first 3 books, which was cool to see (there could be a book 5, I would still read it)
- Honestly, the action in this book and extreme situations (since this book loses a lot of reality) were interesting to read

The loss of two stars: 
- This just went completely off the rails in not the best way, I'm not sure how we got to this society from the first 3 books.
- This book really loses the realistic survival feel of the first 3 books and there is a large learning curve to get into this society, which makes it a bit slower-paced.

Overall: I mean...if you've read the other 3, sure. I do think this can be skipped if you're unsure after the 3rd book if you'd want to continue.
