3.5/5 stars 
 I have to be honest and say that I was very hesitant in starting Frozen for two reasons. The first is that I have read two previous works by Melissa De La Cruz (Au Pairs and Blue Blood series) and really disliked both. The second reason is that some of my trusted blogger friends ended up disliking this book. I take pride in never getting influenced by other people's opinions and ratings when it comes to books but I already had history with this author. Nevertheless, I picked up Frozen and tried to remove any biases I had. Surprisingly, I ended up liking this novel much more than I thought I would. Granted, Frozen is not without any issues and problems, but it was an enjoyable read. 
 The idea behind Frozen was fantastic. I thought a world that has frozen and a time where pirates and slaverers controlled everything outside of the little compound you are supposed to live in is new and intriguing. Of course I'm not for slavery or piratism, but this seemed like new territory when it comes to post apocalyptic/sci-fi novels. Also, the whole phenomena of pollution taking over the world and cities called Garbage Country and trashbergs (equivalent of icebergs but made up of trash) because of the overflow of garbage seemed different. However I do believe, while the concept was brilliant, the execution and progression of the plot had something lacking. Problems were solved too easily. Whenever they are put in a tight situation, the main protagonist and the people with her would easily get out of it scot free. Also, the plot seemed segmented and choppy at times. Especially the ending when a big revelation happened, I personally didn't see it coming because the authors did not give us proper background information or history on the world and the fantasy part of it (the marked and their abilities, the thrillers and their cause, as well as the sylphs). 
 Towards the end when they reach their destination, I wanted a bit more emotions put into it. I mean, they've just reached the Blue.. that mythical place no one believed existed but all I got were descriptions of the nature I see everyday outside my room window. I think that is another issue I had with the book and that is the lack of emotions between all the characters. The romance was sweet, if not a tiny bit insta-loveish but I did like the friendship between some of the crew that helped the main protagonist, Nat, get to the Blue. I do know I seem to have had a ton of issues with this book but I have to point out again that I did enjoy it. It is one of those books that even with all its faults, you still end up really enjoying it. Definitely recommend it to fans of Melissa De La Cruz as well as adventure novel fans.
