3/5 Stars 
 After I finished this book I was conflicted for days on whether I wanted to give it a 3 or 3.5 stars. But after thinking back to how I felt whilst reading this book I feel confident in saying that this was a 3 star read for me. 
 I found this book to be rather.. Underwhelming? For lack of a better word at the moment. I went into this book expecting SO much. I was expecting a light, airy, summer contemporary read that I could fly through in an afternoon. I was met with something much more dense than anything else. By dense I mean that book was a honker, clocking in at 449 pages when not including the bonus content/acknowledgement pages. I didn't think that this book needed to be this long at all. I felt that it was too absorbed in unnecessary details and plotlines that dropped off halfway through the story, which consistently made me question why they were included in the plot as well. I was hoping for a tale about summer friendships and about finding what was lost, and was met with (view spoiler)[ a romance fixated around having feelings for somebody with a girlfriend and still pursuing them anyway (hide spoiler)] and I was expecting a lot more from this book and was disappointed when certain aspects weren't delivered. 
 THINGS I LIKED: 
 + The side Characters (primarily Frank, Collins, and Dawn) were absolutely 
 INCREDIBLE 
 + The storyline of completing the items on Sloane's list kept things very fun, interesting, and feeling like the summer read that I was wanting 
 + The friend group that emerged throughout the book. Dawn, Collins, Frank, and Emily were a wonderful contemporary foursome and Emily's character was slightly more tolerable when these 3 were present in the novel 
 + The way the romance developed closer to the end of the novel. I wasn't the biggest fan of the buildup for some obvious reasons 
 + The inclusion of playlists throughout the story made the novel so much more fun and I found myself making the playlists that were made in this book and listening through them to further put myself in this story. 
 THINGS I DISLIKED: 
 + EMILY AS A CHARACTER, DEAR LORD. I couldn't stand her voice and I understand that she felt abandoned but she put that on everybody else and consistently relies on everybody around her to make her life better and to make her life more worthwhile and enjoyable. The relationship she has with Sloane felt like a platonic rendition of the all-too familiar Manic Pixie Dream Girl Trope. Sloane only existed to drive Emily to take risks and to live her life and it felt so toxic and one-sided. 
 + To add on to that previous point, Sloane doing everything she could to drive Emily to do things she didn't want to do when she knew she was uncomfortable with them and then getting upset with her time and again when Emily showed her discomfort is a huge dick move. Sloane preyed on Emily because she knew that she would be ensnared my how "quirky" and "different" she was. Sloane leaving behind lists for Emily every time she went on vacations and inevitably disappeared without a trace goes to show that Sloane still feels like she has this unshakable hold on Emily and everything that she does. 
 + (view spoiler)[THE START OF EMILY AND FRANK'S RELATIONSHIP IS NOT OKAY. KISSING SOMEONE THAT YOU KNOW HAS A GIRLFRIEND IS NOT OKAY. EXPECTING DAWN, WHO YOU KNOW WAS CHEATED ON, TO TAKE YOUR SIDE IS NOT OKAY EMILY YOU JERK. (hide spoiler)] 
 + The unnecessary plotline of inserting Gideon into EVERY. SINGLE. SCENE. WHY WAS THAT EVEN REMOTELY NECESSARY???? 
 I could go on, I have pros but I have just as many, if not more, cons about this novel. I'm disappointed to have jumped into my first Morgan Matson book and to have felt this way about it. It wasn't a bad book by any means, but after all the glowing reviews I consistently hear about it, I was disappointed to say the least.
