 This book was a lot of fun and a lot of adventure but also a bit confusing not gonna lie. I feel like if this was a hetero book, I wouldn't have liked it as much. There is a lot to love about this book the setting, the adventure, Monty, Percy, Felicity (honestly I just realized I don't remember his sister's name, I sure hope it's Felicity), and of course the m/m romance. 
 I've seen a lot of people mention that it drags a bit in the middle and I would agree. I want to add a bit more to that, I feel like I wasn't getting the book I was expecting in the middle. It felt a little like the Da Vinci Code which is fine! But I was hoping for more boys falling in love and less of the under developed mystery. And tbh that as well as another "isn't this medical thing a plot twist!!!" Kind of made me a little annoyed. 
 I still very much enjoyed the story and I do definitely love the increased rep of neuro disorders but I don't like them as plot twists even though I can understand why the characters did what they did. I'm trying not to spoil anything and I feel like I'm failing lol. But I just want to say that I love that we are having Historical Fiction m/m romances, I love the bisexual rep (ESPECIALLY BI MALE), I love the asexual rep, and I love the diversity in ethnicity. There is a lot to love but that doesn't mean this book was perfect and that doesn't mean I can't point out the problems I had with it.
