It would have been 4 stars but that ending did a fair share of damage. 
 I did not expect to like this story. I have little sympathy for suicide as a general rule since the choice is almost always in the moment over the current drama of life. But reading this was for a challenge so I dove in. And found I really liked the story and the writing style! 
 I really wish Kai did not off himself. He seems like such a great guy based on the letters he sends. He knew Jem well. Although for a guy about to kill himself within a few hours they are too light-hearted and if he can get that clear headed for the letter writing he could have pulled past this if he as waited. SO in a way, the letters didn't feel real for the emotion he was supposedly feeling. Jem I have mixed emotions on. SHe has serious tunnel vision to life and what is going on. From Kai spending less time with her, the party, her own 1 year plans, revenge, etc. She just does not stop and look at the bigger picture so she annoyed me in that sense. But I also could enjoy reading about her. The other characters are not how some seem. 
 All the way to the last few pages I really enjoyed the book but it is amazing how a few pages can make me want to shout "SERIOUSLY?!?!" at it.
