I've been trying to figure out what to say about this book and I'm just so mixed with my reactions. To be clear, I liked this book. It was super cute. The ending made my icy heart melt and say "aw" out loud. But I didn't love it as much as the other books in the series. Josh never felt fully developed or like a full character, I felt like his role was purely to be the love interest. Etienne and Cricket had developed from friendships into a romantic relationship with the girls, Josh goes from crush to instant love? I just wish there had been more friendship building first to develop more of the other feelings not just the passion and love. 
 Isla. Oh Isla. I thought she was younger than she was, like maybe 16, but no, she's 18 and kind of immature. I felt bad because I have acted like her in my first "real" relationships- the jealousy, the keeping fears quiet, the obsession- so I know how it happens. But I also know that eventually I realized that it didn't work and guys aren't into it. And guys just aren't into it...but Josh was? I wanted to go into the story and tell Isla "Just speak up. Feeling jealous? Say something. Feeling scared? Say something. Use your 'I' statements AND SAY SOMETHING!" Honestly, I don't see the relationship lasting forever but maybe that's my cynical outlook on my previous relationships. Remember, I used to act like Isla. It never ends well and then you grow up. 
 I also felt like the story had a lot of cute moments but the plot between those moments was lacking. Like Barcelona? So cute and wow. The Ball? Cute! The parts between these big adorable moments were lacking and kind of sad. Which isn't to say I didn't like this- I did! But I was hoping for more of a storyline other than obsession and waiting to go to the next big moment.
