4 stars. 
 This book was really really cute. 
 When I started it, I felt like I was going to end up being really disappointed in the book, but as it progressed I found myself falling more and more in love with the characters and Simon and Blue's relationship. (Just to make it really obvious, it was really adorable). 
 I really loved how the book was very realistic (in my opinion). The high school setting seemed pretty normal, his thoughts were normal, the dialogue was normal and the characters acted in realistic ways. I didn't find myself getting really annoyed or frustrated about anything which has been pretty rare for me recently. Woo!!!!! 
 Also this book was funny and smiley and gave you all the feels. 
 If you're looking for a cute, contemporary, definitely pick this one up!
