This book was entertaining and the prose had me from the start. The increasingly delusional choices made by Javier make for a tense yet funny read. Interesting concept, made me think of Yellowface a bit.

What I didn't love about this book was the ending and the relatively flat character that Javier is. I saw a review from another reader that pointed out how Boryga could have made an even bigger impact by taking the time to let Javier's real, actual trauma be explored. Javier's entire story and personality is his white-guilt-trauma-porn grift and as the book goes on, he becomes increasingly flat as a character. A lot more could've been achieved by contrasting the made up stories with the actual trauma/difficulties Javier faced but seems to care little about (witnessing his dad's murder, struggling to keep up with the rigors of college, etc). I almost feel like Gio is more fully fleshed out than Javier. 
The ending was too after school special for me. Javier has his come to Jesus moment and gains deep, valuable insights about his bad choices and what he's learned from his experience. The book wraps up so quickly and cleanly that it was a a bit of a letdown. 

All that being said, the writing is sharp and engaging and there's some interesting commentary. I found this book to be entertaining and say it's worth the read.
