Probably going to have to disagree with the other reviewers who've said the beginning was too slow. For some reason I really quite enjoyed the beginning; I thought it did a fairly good job at fleshing out the characters' motivations and emotions. Towards the middle and the end is where I started skimming, because the characters started losing me. Not sure why, other than the fact that I was mildly annoyed by their justifications for their actions and emotions.
Things I liked in this book: the basic premise of the story, the character archetypes, the fleshing out of the somewhat cliche plot devices to make them less unbelievable
Things I didn't like as much: the characters themselves, the way they interacted with each other, the way the manager's character seemed to have gotten dropped despite getting some pretty decent buildup in the beginning
