From the small section of the book that I viewed on Amazon, I have reservations about going any further, not necessarily because of concerns about the story or plot, but because of the writing itself.
The writer spells too many things out - telling the reader, not showing the reader - something that gets very wearying very quickly and is a surefire sign of inexperience. One line for example "as he pulled into his driveway, George became embarrassingly aware of his own sellout to consumerism" - oh, really? How did this manifest itself? Why can't George pull into the driveway and at least wonder what he was doing in a place like this, maybe mutter it sotto voce, there has to be a better way than just telling the reader how George felt - make him real by making *him* tell the reader instead - through actions or interior monologue. There are many more nuanced ways of introducing a character's sense of their own situation than simply spelling it out, and they generally make for a better read. Readers like clues, they like to be able to "guess ahead" and are driven not by the things they've already read, but by the things they need to discover as they go along, the unresolved stuff, not the things they were simply told by the writer. Other moments in the book have the same ring, unfortunately. The tendency to mention makes and brands is another thing, most readers can picture a typical truck, but do they really need to know it's a Ford? If this isn't important, drop it. It's the kind of thing beginners do and leaves the reader wondering whether they should look up info about it, because it's obviously important that it is a Ford; it's like giving an incidental character too large a role - it sets up expectations that are not going to be fulfilled. It matters more whether a truck is beat up or shiny, that actually tells us something.
Reader comments about the implausibility of some scenes also tend to confirm this uneasy feeling that the whole thing is not thought through. While I'm reluctant to dismiss anyone's work out-of-hand (I've very aware that these things matter to the writer) there are too many reasons not to read the story, and the suspect reviews are one aspect of that.
As a pilot, I'm also interested in aviation but will probably stick with my old Brian Lecomber adventure novels in the aviation milieu. They also have their weak spots, but the writing is generally solid and the aviation, although it permeates the books, doesn't dominate the underlying stories and solid characterisation.
