First of all, this was my first book by Kasie West that I've read and I'm in love with her style. Her other books have now maneuvered their way to the top of my TBR. Second of all, this book was just...GAH FEELS! 
 It has one of the greatest premises ever and I'm beating myself up for not thinking of this idea before Kasie did. In a nutshell, this book is about a High School Junior, Lily who writes songs as a hobby. She writes song lyrics from her favorite band on her chemistry desk then the next day she finds that someone has written the next line to the song on her desk and also left a letter. Her and her anonymous pen pal start exchanging letters everyday and she starts falling for the mystery letter writer through his letters. 
 Lily is different and hilarious as she is constantly sarcastic. She doesn't care a lot about her appearance or the way people perceive her. She is most focused on her creative side with songwriting and music. Which I related to her so much since she refers to her guitar as her "baby" (I love my guitar). I enjoyed her a lot and, like I just mentioned, found her very relatable. 
 I like how there was a close female friendship in this book between her and Isabel. They had small fall-outs here and there but they never held grudges for long. I thought they were the ideal friendship. 
 We'll get to Cade later in the spoilers hehe. ;) 
 Okay, back to the point: She also got into a few encounters with some guys. Her crush Lucas seemed cool but I never felt a spark with him. (view spoiler)[ She mentioned that she found out that she was more in love with the idea of him but really didn't know who he was at all so she broke it off with him. And I'm glad she didn't end up with him because I saw no potential there. (hide spoiler)] 
 I found David more interesting than Lucas but never really liked them together as I didn't see a connection and I also shipped her with someone else haha. I realized after finishing this book that he wasn't mentioned a lot for the last half of the book. It wasn't a big deal but I just found it odd that he fell off the grid. But, eh, I wasn't a big fan of him so moving on... 
 The family dynamic was so strong and great in this book. Great family relationships are so rare in YA and it was nice to see one in this story. Lily's family is crazy and out-there and never gives her the time of day to be by herself and work on her songs. But of course, she loves them anyway. And her relationships with her older sister and two younger brothers is so sweet. 
 As I mentioned earlier, the plot was fantastic. Predictable, yes, as I figured out who the letter writer was about five chapters in, but still enjoyable. And unexpectedly suspenseful! As I figured out who the mystery pen pal was, I was anxiously waiting for a confrontation once she discovered who it was as well. But she never approached him about it. There would be times when he would almost figure out and then wouldn't and I felt like screaming, "Come on, it's so obvious!" Talk about frustration. But the payoff at the end of the book was great. 
 Okay, so let's talk about who the mystery writer is. (spoiler time) 
 (view spoiler)[ I was so happy that I was right and it was Cade because I LOVE relationships where two characters initially hate each other and then they fall in love with each other. I feel like they add room for so much character development between the two and they're just so fascinating and sweet. So I was hoping if all goes well, Cade and Lily would fall in love and I was definitely satisfied when they did. 
 Because of my love for hate/love relationships, when they finally got together, I couldn't stop smiling. And the way they got to know each other through anonymous letters was brilliant. They hated each other so much but when they wrote to each other, not knowing who was the other pen pal, they got to know each other so well. Which in turn, after they found out who they were writing to, realized that people put up walls and that not everyone or anything is as it seems. It was just beautiful. Imagine if they get married (and have indie rock babies lol) how great it would be to tell their kids how they fell in love. WE NEED A SEQUEL ON THAT! (hide spoiler)] 
 Alright...so that's all for my fangirling over this book. I would definitely recommend if you're into cute , contemporary books. I can't wait to read more from Kasie West, I think she's my new favorite!
