I have been putting off writing this review since I turned the final page of this book. 
 Not because I didn't enjoy it or because I didn't have strong enough feelings, and certainly not because I didn't feel like talking about it. None of those are the case. 
 I haven't been able to write this review because I just have 
 SO many feelings 
 about this book and about every single character! 
 I went into this book knowing full damn well the premise and that it would be foolish of me to get emotionally invested in these characters. 
 But I am a foolish mortal, and emotionally invested in these characters, I became. 
 I was so enthralled in Rufus and Mateo's story. Both their separate stories and their combined story once it began. I just couldn't help but to fall in love with these two boys that I know I would lose by the end of the story. Adam Silvera's characters are always so beautiful and authentic and so wonderfully fleshed out, it's hard not to fall in love with every single one of them. In most YA contemporary I feel like teenagers are given these vocabularies of 30 year old authors and it just doesn't feel like believable dialogue in the story, but the dialogue between these characters is not only hard-hitting and poignant, but is also exceptionally believable as the dialogue between teenagers. I loved the bits in each boy's perspective, as well as the third person points of view of other characters that are effected by DeathCast and the calls they make. Their wasn't a single character or aspect of this story that I wasn't interested in. ALSO LET'S JUST TALK ABOUT THE FACT THAT ADAM SILVERA DID THAT TO MATEO HE DESERVED SO MUCH BETTER AND I AM STILL NOT OVER IT, NOT EVEN A LITTLE BIT 
 The side-characters that surrounded Mateo and Rufus were also wonderful editions to this novel and each brought something different and special to the table. The interactions Rufus had with the Plutos as well as Mateo's relationship with his best friend and to his father is one that tugged on my heartstrings every time I read those moments. (view spoiler)[LISTEN MATEO IS AN ANGEL AND THE SCENE WITH HIM AND HIS FATHER IN THE HOSPITAL STILL HAS ME FUCKED UP ADAM HOW COULD YOU DO THIS TO ME (hide spoiler)] 
 The way all of these characters have these stories that mingle together and being able to see how all these stories effect one another goes to show the little impacts that strangers on the street can make to another person's day. It shows that while we may be living our own life and going through our own things, the people that we pass by without giving thought are going through their own struggles within their life as well. And seeing all of those come together in this perfect melting pot of a story was such a wonderful and thought-provoking thing to read about. 
 The overarching theme of this story, of mortality and how humans come to accept it (or not accept it) and living life to the fullest is so beautiful, in the most heartbreaking way possible. To imagine a world in which we are called the day that we will die is so interesting to think about. 
 I could not gush about this book enough, any little issue I had with this book was not one great enough for me to knock my rating down anything under a 5-star. This book has continued to stick with me since I turned that final page. Adam Silvera continues to play my heart and emotions like a tiny little violin and each time, in a midst of ugly crying, I thank him for it.
