I'm still reeling and on a high from what was a very wild ride, but I'll try to put together some of my thoughts. They're going to be a jumbled mess, be warned. 
 I thoroughly enjoyed this book. This was a book I borrowed from the library because I was wary of the formatting, but now I'm desperate to own a copy of my own. I'll admit that some of the page layouts were frustrating at times (view spoiler)[flipping the book up and down and around to try and read some of the text was a little bit difficult on the cramped bus home from uni, but I got there and it was worth it! (hide spoiler)], but I really enjoyed the layout and formatting of the book overall. 
 The story itself wasn't anything entirely new: corporations in space, biological weapons in space, crazy AIs (it's not a spoiler, don't worry, this is all on the back of the book!), but I just really enjoyed the way it was executed - Aidan's pages, in particular, were my absolute favourite. Honestly, his/their/its(?) pages are what earned this book a 5/5 rating for me; every time I found myself turning to a black Aidan page, I was doing happy little cartwheels on the inside. I got a little bit bored with Kady and Ezra at times, but towards the end of the book I really found myself connecting with Kady, in particular. (view spoiler)[Those scenes where she was fleeing the afflicted and struggling to fight, and dealing with Byron and Ezra and, ugh, that poor girl. Let her be happy. (hide spoiler)] Additionally: (view spoiler)[Those pages where Chatter and Syra are talking, and then he mentions the sick passenger, and then it cuts to the log where it outlines the purging... I had to put the book down. It hurt. (hide spoiler)] 
 I've only just noticed that there's a sequel coming and I cannot wait. In summary/tldr; 5/5, do it for Aidan.
