I was mostly ambivalent towards this, except for the end. But I'll get to that in a minute. 
 I found most of the book... kind of boring, to be honest. There's no way, with a premise like this, it should be boring! And don't get me wrong, I'm a fan of the narrative style of book--interviews and transcript logs--but it never felt authentic for me. It felt not just gimmicky, but poorly executed. It's no where near the caliber of World War Z: An Oral History of the Zombie War or even Robopocalypse. Or hell, even Illuminae. 
 There were times when characters would be recalling events that happened previously and the staggering detail of some of the recollections was just... quite literally unbelievable. And immersion breaking. If you need that much detail to sell the scene, why not have it told in a different way? Why not actual use a more standard prose style? 
 And ugh, the characters. Listen, I actually liked our nameless, all-knowing interviewer. I know he's a problem for other people with less than favourable opinions on this book. But I enjoyed him. But I'm sorry, some of the ways grown-ass adults behaved in this was ridiculously juvenile. It's another flaw of the weak writing, I think, but the characters aren't driving this plot. Not really. Certain things have to happen so, oh yeah no totally a character does that, definitely. I don't buy it. 
 It's not necessarily a bad thing to have a plot that drives the story like this, but it never felt organic to me. And parts of it were really slow. It picks up a bit just after the halfway point, but then veers off into "wait what?" territory again. 
 I was reaching the end of this book, certain of my 2-star rating and that I probably wouldn't read the next book when that epilogue happened. And instead of being thrilled about that intriguing ending and twist I'm mostly just angry about it. Because it makes me want to read book 2. And I just don't know that I won't be as happy reading spoilers on the internet. So. We'll see, I guess.
