Main Female Character : Julie - Easy to relate to and caring. 
 Main Male: Matt - Very nerdy and quirky, but funny. 
 WHAT I LIKED: WOW, JUST WOW. I weirdly got hooked into this book pretty quickly, and as soon as we met Celeste and Flat Finn, I knew I would love this book. The characters all have so much personality, and it's easy to see yourself in everyone. I had mostly figured out the twist by the middle of the book, but I didn't mind, and I didn't have all of the information. For me, the book felt very real, and I believed the story. I also loved the witty banter. I laughed quite a bit! 
 WHAT I DIDN'T LIKE : I guess I didn't understand how Julie went from months of anger to suddenly willing to forgive. And while I REALLY loved the developing friendship instead of insta-love, I would have liked a little bit more sexual chemistry to really believe it. Both of these complaints are VERY minor, considering my deep love for this book. 
 RATING: A rare 5-stars. This book worked for me on so many levels, and I already can't wait to read it again. I'm also looking forward to reading Flat Out Celeste!
