** spoiler alert ** 
 SPOILERS!! Don't read if you haven't read this book. I'm not going to tell you who Blue IS, but I've written a bit about who Blue ISN'T. 
 I really enjoyed this book. It was very squee worthy, there were times where the cute overload made me actually squeak outloud and hug the book. 
 Simon is the best character ever, he's so cute and funny and relatable! I liked how he explained his family, because you can tell that he really loves them even when they're driving them nuts. I wished we'd gotten to know his sisters a bit better. I dislike when authors make characters but don't really flesh them out, which happened a lot with most of the characters that weren't Simon or the people Simon was into. (And Abby. I love Abby). 
 I really, really wanted Blue to be Nick, even when I was far enough into the book to realize that there was no way he could be. I just thought that this book was so cute and sweet, and wouldn't it be just perfect if he's fallen in love with his best friend, like in a romantic movie? I know, I'm hopeless. 
 I liked the take on cyber-bullying, which wasn't what I was expecting when I picked this book up. I really liked how Simon voiced his hurt over it, how Martin stole something from him, and gave something of him away that he wasn't ready to give. I wanted to reach into the book and hug the kid. 
 Please read this book, just trust me on this one.
