I guess it's telling how much I enjoy a book by how quickly I get through it. This one took me one day. 
 I want to say that young adult books focusing on gay protagonists are a guilty pleasure of mine, but there's nothing guilty about it. I openly adore these sorts of books, maybe because it reminds me of my own confusing adolescence, maybe because I didn't know how to find these books when I was a kid or maybe it's just because they're really well written and entertaining. 
 Because I'm a fan of the genre I can't help but compare it to books like Aristotle and Dante Discover the Secrets of the Universe (which is getting a sequel?! Holy shit) by Benjamin Alire Saenz and I'll Give You The Sun by Jandy Nelson. 
 And it stands up, Simon was an imminently likeable protagonist and his surrounding friends and family all felt realistic which can sometimes be difficult to pull off. Particularly Martin who needed to be a villain to some degree. 
 Now for some spoilery thoughts.

 Like I mentioned Martin was an interesting character. He straddled that line between despicable, pathetic and almost sympathetic. In no uncertain terms Becky Albertalli shows that what he did was unforgivable. Simon sees that, we as the reader sees that but importantly Martin doesn't. That sort of thing happens all the time being gay. Of course being outed as gay isn't such a big deal these days, but it's fucking important to the person. They have to do it on their terms, being forced out is literally the worst thing you can do to someone in the closet. 
 Something that can be forgotten is that when you're gay you don't just come out once, you come out every time you meet someone new. You don't have to announce it, but there's always the thought at the back of your mind that this person doesn't know and at some point they will. That's coming out, whether it's deliberate or not and it can be exhausting. 
 I like that Martin realised his mistake but I liked it even more that Simon didn't forgive him. It was certainly left open for the chance that Simon would eventually soften his position, but I think it's important it didn't occur in this book. 
 As for Simon's fleeting thoughts that Martin might be Blue, I'd dismissed that almost immediately because it would be too much of a stretch to suspend my disbelief in that case. But, not being as genre savvy it makes sense that Simon would consider it. 
 I liked the red herring of Cal. Particularly because he turned out to be bisexual rather than some farce-like mistake. I also liked that Simon had a chance with him but didn't want to because he wasn't blue. 
 As for Blue, it was round about the time that Simon in his sexy makeup noticed Bram was looking at him that I realised he was Blue. Though I still don't know which superhero he shares a name with. It was nicely set up, he was always there but not in an obvious way so when I figured it out, it clicked into place. I'd considered him quite earlier when Simon ponders the situation but Cal Price kind of took over the focus. 
 Simon really does freaking speak like he writes so it's no surprise Bram figured it out. 
 I think I'll get a lot of out this when I eventually re-read it. Throwaway lines like Simon thinking all Jewish people must have Israeli heritage shows why a black Jew would be a blind spot for him. 
 I got really angry at Abby when she practically victim blames Simon for complying with being blackmailed. I got even angrier at Simon for accepting that accusation. I softened my view when Abby basically admits she shouldn't be so hard on him because of that, but it still annoyed me at a character level.

 In summary, I read this over the course of one day, I loved it and recommend it to anyone who is a fan of the genre (and thank God this genre exists).
