What started as somewhat of a contemporary about a young girl changing her life for the better turned quickly into a page-turning thriller about revenge, mistrust and, as expected from the title, the impending end of the world. Olivia was a somewhat naïve girl who, in trying to become more outgoing, found herself completely wrapped up in a potentially-final summer that she absolutely didn’t sign up for, and it was fascinating to see her react to her situation in exactly the way a somewhat amenable but intelligent teenager might.

Natasha was a fascinating character, and my opinions about her changed back and forth so rapidly that I spent the majority of the book completely confused as to how I should feel about her. There was a side of this to most characters in this book, including Olivia’s mother even, so I was completely hooked and desperate to find out who to trust the entire way through.

It was hard to figure out where this book was going but the ending did not disappoint. Although I found some of the recapping and discussion towards the end slightly unnecessary, I was so shocked by some of the twists that the book didn’t lose its page-turning quality for a second, and I felt that the story was wrapped up and explained fairly tidily when everything was finally revealed.

This was a really fun, unputdownable story that combined the excitement of a coming-of-age contemporary with the suspense of a thriller. It was fast-paced and completely unpredictable and, if you’re looking for a book to devour in one go or a thriller to get hooked on, I would absolutely recommend it.

Rating: 4/5
