Not completely convinced. 
 The good: 
 - it's a page turner for sure, and it'll keep you reading well past your bedtime, and you can get so into it that you'll nearly forget about the book's flaws ; 
 - the way the story is structured, even though it makes for an uneven pacing. Most of the flashbacks and aside do come to fruition at the end, although that doesn't make them completely necessary and I still think the book could have been shorter by at least a couple of hundred pages (and that's from someone who LOVES long books); 
 - the action scenes were pretty well written. 
 The bad: 
 - a main character who, for most of the book, manages to be quite bland AND a Gary Tsu at the same time (is there one thing this guy is not good/the best at ?); 
 - too many underused secondary characters; 
 - THAT'S NOT HOW FIRST PERSON POV WORKS!! Seriously, take a page out of Andy Weir's The Martian if you want first person AND extremely detailed narration of things that happen outside your protagonists' scope. Suspension of disbelief is reaaaally hard to maintain when you repeatedly describe things that your protagonist has no way of knowing in so much detail. Sorry, but that really peeved me. 
 - antagonists that are not very convincing at the best, cliche at the worst. And again, underused, or used in a way that does not make them as fascinating as the author seems to think they are. 
 - generally, I just didn't care about the characters, there was almost no emotional connection most of the time, to me anyways. 
 So... will I read more if there's a series ? Possibly, but I wouldn't bet on it. 
 Will I watch the movie ? Probably, because if well done it will certainly solve most of the pacing issues and I might get to appreciate the story more then.
