This is a five star rating that makes me reevaluate every other five star I've given this year. 
 The Good: 
 There are a lot of YA books that try and tackle several big topics and fail miserably. I was nervous as I started this one because it was tackling bullying, grief, and abandonment. Then it added mental illness, suicide, and abuse as the narrative progressed. Those are huge and important topics. I never felt like one subject overwhelmed any of the others. The writing style is effortless and engaging, and as I fell into the story, the issues layered over each other in a way that felt natural. Each issue was handled respectfully and fully, exploring it from every direction. The characters made smart choices, and the issues were handled intelligently. For example, one of the characters bullies our main character, Henry, for reasons that are explained early on. It's an expected reason, and one we see a lot in lgtbqia+ narratives. However, it's never used as a justification for that character's behavior. It broadens him, but it is never used to excuse his actions, especially later in the book when things get a little more intense. 
 All of the characters are very well done. Henry has a lot to work through in this book. He's mourning the loss of his boyfriend and questioning everything about his life (except his sexuality which I really appreciated. That was the one aspect about Henry that was never questioned. He embraced his sexuality in a very healthy way). The driving force of Henry's story is about whether or not the Earth is worth saving or not. He grapples with this constantly, and challenges his friends and family to help him come to terms with what his answer will mean. 
 Diego is a wonderful love interest. He has his own issues, and I loved the space Hutchinson gave them. They were revealed slowly instead of jamming all of his backstory into one chapter. I also loved that Henry and Diego's relationship hit realistic obstacles. Instead of lying to each other or avoiding each other, they each took some space and would then come back to talk about it. HEALTHY. 
 Audry is also lovely. She doesn't get a lot of space for the first third or so but once she and Henry had their moment, I was all over this friendship. She's protective, intelligent, and loyal. She supports Henry unconditionally and is there for him when he really needs it. 
 I'm a sucker for stories that handle mental illness and death well. I think my one gripe is that I wish depression had been teased out just a touch more. Now that I've read the ending, I see how Henry's is interlaced through the narrative but I wanted a little bit more. 
 Also, because it's absolutely worth noting: 
 (view spoiler)[I absolutely love how the attempted rape on Henry was handled. Sexual assault on men is RARELY discussed so slow clap for Hutchinson for bringing it up here. It wasn't sudden; there were clear hints leading up to it. But I'm so glad this subject had a minor spotlight. It doesn't get nearly enough attention in the real world. (hide spoiler)] 
 Overall, I loved it. I really did. I have to buy this one so I can have my own copy. Plus, look at that cover. It's gorgeous.
