This one started off rather unspectacularly. I kept getting frustrated that nothing was happening that really made me care. I was full of "meh..." Then, maybe about 40% in I started getting intrigued (view spoiler)[More about Marina's story than John's (hide spoiler)] and I was glad I stuck with this story. 
 Vague Spoilers to follow: 
 In the beginning I couldn't stand Marina's story because I despised Adelina. Like I wanted to kick her butt. Seriously. But as the story went on, and I learned more and more about Marina, I wanted this whole book to be about her story. By the end I really liked her and totally was rooting for her. (view spoiler)[Hector Ricardo! He always spoke in the third person which was strange but made him a lovable weirdo. Ella! NUMBER 10!!!! Ahhhh! (hide spoiler)] 
 I found much of John's narration to be uninspired. Remember when I thought John was a genuinely likable character due to his goofyness? Not so much in this book. Is it just me or is he totally selfish to the point of idiocy in this installment? The real saving grace of his side of the narration was Six. I love her. Total badass heroine. No damsels in distress here! (view spoiler)[ I was really glad Six went to Spain to help Marina. At least now (If Marina is still narrating in the next book) I will get Marina and Six in the same narration sections which will be amazeballs! NINE!!!!! We found him! Sam! NOOOOOOOOO! I loved my nerdy little guy. Can't believe he got left behind with the Mog's! (hide spoiler)] 
 I gave this 4 stars mainly for all the Marina sections. It had some spectacular action too. I will definitely be moving on to book 3.
