This is certainly a page turner - the plot moves very quickly (standard for this style of book), the chapters are short (averaging about 3 pages each) and there is enough action to please most readers. The storyline is very current - both Bradley Manning and Edward Snowden are mentioned - and the plot, while not likely, is not as far-fetched as some in this genre. Jed Walker, the hero, does perform some acts which push at the boundaries of suspension of disbelief, which is, again, pretty standard for this genre, but certainly doesn't go as far as Matthew Reilly's Scarecrow, who completely destroys those boundaries.
The copy I have is a pre-release, uncorrected proof reading copy, so there were a few spelling and grammar errors that I hope will be corrected before its release in late November. And there was one error which will horrify the mathematically literate, or even semi-literate, among the readers - when Newton's 2nd law of relativity is referred to, which doesn't exist. What they clearly meant was Newton's 3rd law of motion.
But, overall, if you enjoy fast-paced military-political thrillers, then you'll likely enjoy this book.
