Usually, I would start by saying how disappointed I was with this, but this honestly has me infuriated. This goes so far to standalone from the first book that it almost completely disassociates from that world. Congrats! You don't have to have read the first book to read this one.
Having read the first one, though, just a few weeks ago, I thought there would be some kind of plot or timeline alignment. I wanted the campfire scene from the first book to be a catalyst for Kyle and Phil getting together. It isn’t. In this retcon, that fire likely never happened. And now, in this, Kyle isn't a homophobic dick to Jon so we never find out WHY Kyle was such a homophobic dick in the first book. Then there's Simon, the villain of this tale, who I thought had to be the same villain from the first book expect THAT was Martin. The only friend Victor had in the first book was Martin. I literally went back and reread the first book to confirm that there was NEVER any mention of a Simon. Who is Simon, where did he come from and WHY DOES HE READ LIKE HE'S MARTIN?!!!! I feel like the author just forgot the name they gave the character from one book to the next and it was driving me nuts.
Also adding to my aggravation is the Fifty Shades reference. Jon From High School was published June 2020 and has a 10 year gap in the story, putting the characters in high school 2010 or earlier. Fifty Shades wasn't self-published until 2011 and didn't start gaining infamy until it was picked up by Vintage Books in 2012 so the idea that a pair of high school boys in 2010 would know about it to reference it in this book is just STUPID. It would have been equally ridiculous for them to reference the Twilight fanfiction series that Shades was adapted from, but if they had done that it would have at least been consistent with the timeline set by the first book.
Ignoring all of that and treating this as a standalone story, we get to the worst part of this read. The barn. The way that storyline took over this book about two seemingly underage boys is disturbing especially when there's no relevance to their future. It wasn't what brought them together and, thank God, it wasn't the way they chose to be together as adults, so what was the point unless it was to make Simon/Martin an overarching villain in this series -which would make sense because Martin has a book and it's saved for the last installment of this series. If that’s the case, though, then all the books connect, this isn't a true standalone and it should sync up better to the first book!
TLDR: I hated this book. If you read and liked Jon's story, SKIP THIS! Honestly, just skip this period.
