Alright Soooooo. Apart from the obvious reason of tension between a certain two characters, I liked this book.
The whole route 66 vibe, the exploration of what happens to hero when he doesn't feel like one and the complexity of relationships was amazing.
It's not AS good as Carry on but it's not bad either. I'd give it a solid 4.3/5.
I'm also really excited for the third one coming on July 6th and also very scared cause I hate endings ¯\(°_o)/¯
