For the first twenty or so pages, I was really into it. It was adventurous and full of action. Then Callum entered.
From that point this became less of an adventure book and much more a romance story, which was weird, since in the beginning it had been made very clear that Wren didn't have much emotion. It seemed unbelievable that Wren would go from no emotion, to "I'M SO IN LOVE" almost overnight.
For the second half of the book, there was so much kissing. Usually it's swooney and great. It was not. They kissed when they were in danger and should be running for their lives. They kissed all the time, and it got so annoying.
All in all, it was an interesting idea, but focused way more on teenage romance than the dystopian side of the novel. I know I would have liked it a lot more if Tintera had just toned it down a bit.
