All of these people in the book constantly praying for escape from one dire situation or another, and then not one of them thinks to thank God when they are delivered?
The book has some genuinely good things in it. A couple of beautiful moments, a few apt psychological insights, a text that seems to have been proof-read: there are refreshingly few spelling or grammatical errors, aside from an inexplicable few chapters where the tense strangely wavers between present and past (???), and it is a fast-paced, action-filled story if that's what you're looking for.
On the other hand, there are some very silly things here as well. I could cite several examples, but not without introducing spoilers into this review. Aside from the nonsensical bits, the non-stop action comes at the cost of a healthy dose of deus ex machina and frequent insistence that you suspend disbelief in the ability of dead or mortally-injured people to nevertheless keep going strong within minutes of their injury or death. There are some relatively skillful descriptions of traumatic experiences, but each time a character experiences a similar trauma, the descriptions are very similar. For instance, it communicates terror when a character comes so close to being shot that they feel the bullet's displacement of air as it passes. But when characters repeatedly experience the displacement of air over and over again, the reading experience is suboptimal.
