Okay, so this is Bad.
(I have a lot to say, both about the book and its author and the fandom circulating around both, but I will start with the book.)
There is absolutely no world-building. The reader is violently catapulted into this fantasy/magical version of modern NYC. There are people called celestials (they have powers) and also there are specters (they also have powers, but they got them the Bad Way by drinking magical creature blood) and there are Spell Walkers (who do god knows what. Seriously, they go after specters and celestials, but no reason is given. like what the fuck is their purpose?). Adam Silvera has an entire fantasy world up in his head, with absolutely no way to communicate it. And, frankly, that's very disappointing. This is his fifth book. He should know how to clear things up for the reader. And also, he states in his author's note that he has wanted to write this book for 10 years. That is more than enough time to put together a brief explanation as to what the fuck the point is of all these people with powers.
Now let's get to the characters, Emil and Brighton. It's like Adam Silvera split up his personality, and projected them completely onto them. He tends to do this in all of his books (especially in What If It's Us...), but here, it's just downright cringey. Neither of the main characters is likable. All they do is whine about unimportant shit, and they're so self-absorbed, I want to hit them. I got to page 100 and realized I could not connect even the tiniest bit with either, which is just bad character writing, plain and simple. If by page 100 in a 300-page book, the reader still feels like the main character is a complete and total stranger, you're doing it wrong.
Now to the really important thing: This book shouldn't be successful. From what I read in the manuscript, it was rushed, poorly executed, and there was a complete and total lack of communication through the narration of the author's ideas to the readers. But knowing what happened with What if it's Us, this book is going to be a hit, and here's why: Because it features a gay poc romance.
I believe in representation. I believe it is important to shine a light on lgbtq+ relationships and ESPECIALLY lgbtq people of color, and their stories. I believe full-heartedly that there should be more books about heroes who aren't cis, straight, and white. But I also believe in good writing. And I think that lgbtq characters of color deserve to be in well written, well-developed books. Not this. Not anything like this.
To me, I feel like this book will become popular not because other lgbtq teens of color read and enjoy it (although if they do, it is fine, this review is just my opinion), but because 13-year-old cis straight girls who fetishize gay romance will read this just so they can add Emil to their "my gay sons" list. It's gross, and it's weird and it's disgusting, but it's the truth. Adam Silvera's books feed this particular audience; I have too many memories of bookcon when What if it's Us was coming out, all of them filled with me cringing at cis, straight preteen girls squealing over the fact that they had the chance to win an ARC of a gay romance book. I did not see ONE lgbtq person of color reacting to the book in that way. It was loved only because it featured a mlm relationship-- one that was, by the way, extremely unhealthy, with both characters being obsessive and weirdly possessive with one another, and their arguments being so nasty, I consider it to be verbal abuse. They feed off of it, and it's despicable.
I read the Infinity Son manuscript and only made it through 150 pages. That's halfway through the book. I did not like this book. Simply put: Adam Silvera should be better at writing by now. Yet this book reads as if it's the very first words he's ever written down on a page. There is no development of characters. There is no world-building. There is no clear, concise explanation as to what the fuck everything is in this new, magical world. There is only confusion, and random, dramatic cliches hrown in just for shock value, or for an easy explanation that doesn't require much thought. Things happen out of nowhere. Nothing makes sense. Nothing in this book has a purpose. This book has no direction. It's predictable and just plain wrong, and I really hope other people see that, too. But no one will say this for fear of looking mean. I think there are other lgbtq+ authors who are also people of color who have books and stories to tell, but they don't have the following or the means to share their books to the public in such a widespread way that Adam silvera does. This in itself is an injustice; we should not continue highlighting the same voice when he continues to fail and fail again, we should be branching out and discovering new talent that can actually shed a positive, beautiful light on necessary stories, like what Infinity Son should have been.
