To be honest, I picked this up purely because it started with a Z. (I'm aiming to read two books from each letter of the alphabet this year.) The fact that it was a fun read was a bonus.
The author is a career pilot, so I was surprised there isn't more plane porn in the book. There was just enough to let you know the details were right, and certain small points of the plot hinge on aspects of planes, but if the one-sentence explanations weren't there you'd never miss them.
This probably wasn't the best choice to read while flying during the dangerously stormy weather that blanketed the country this week (July 1-6 2013), since it starts with an airplane getting struck by lightning. My initial flight was actually cancelled due to heavy weather. Plane crashes factor into the plot, of course, and there are a number of them. It didn't help that as I sat in O'Hare reading the last few chapters, a plane from China crashed and burned upon landing in San Francisco.
I also had two of the bumpiest plane rides in a long time. All of which should have lessened my enjoyment of this novel, but it moves right along, enough to distract me from the outside world. (As I write this, it looks as if two 16-year-old Chinese students died in the SFO crash and a hundred people are seriously injured. I don't want to minimize the tragedy by making this all about me. I don't do prayers, but my condolences go out to those affected by the Asiana Airlines flight 214 crash. I hate to say "it could have been worse," but it sure could've been.)
Back to this book.
I like how Donlay subverts the usual trope of a wealthy man teaming up with a beautiful, competent woman (sometimes in these books it's a scientist, here it's an FBI agent) as they are thrust into a situation neither had anticipated and is bigger than they suspect.
The characters aren't particularly deep, but they're far more complex than the usual ones you find in thrillers, so I consider that a bonus, too. For these types of genre books, anything that goes slightly above and beyond the normal cliches is grounds for an extra star. Donlay does this a couple of times on the character front as well as on the plot front. And even though everything is wrapped up by the end, it's not exactly a happy ending.
I especially liked the main character, who is more true-to-life than most of these wish-fulfillment types. He's really good at one thing, not bad at a couple others, and not so hot at a whole bunch of stuff. Just like normal people. Usually these guys are all James Bond-alikes, expert at everything.
Anyway, fun book, easy read, with a bit more to it than the usual thriller.
