 First, can we please just take a moment to appreciate this cover. I love it! I think it was absolutely brilliant how the first everything is emptiness and the second one is full of nature. It's smart, beautiful, and a perfect representation of the story. Whoever did this, I applaud you. 
 Now to the actual story: I liked it, but didn't love it. I really liked the characters. Especially Olly, who usually had me laughing or swooning over his hotness. 
 I also liked how our protagonist Melanie loved to read! I love it when characters share my passion for reading. 
 The plot was really interesting and original, but a tiny bit predictable. It wasn't very difficult to see what was going to happen. There was one big plot twist that did take me longer to see coming, but it still wasn't that big of a shock to me. 
 I think that the ending was really abrupt though, and I wish it had gone on for a couple of pages more. It just wasn't very complete to me. At all. 
 Also, I read this book free online, and did not realize that there were supposed to pictures in it until I finished the book. I am now extremely disappointed because the free online version did not have the pictures, and I feel like I kind of missed out on the full effect of the story now. So, if you want to read this book, I suggest reading an actual hard-copy of it - don't read it online! So, now I will probably buy myself I copy of it and read it again in a few years, with the pictures and all. Who knows, maybe I'll like it even better with them.
