This is a good, page-turning, sci-fi, thriller. I would say it is in line with the Dan Browns and the Grishams of the world.... but the writing is a little bit novice. The author is quite adept at enticing the reader to turn the page to find out "what next?!" However, it seemed apparent to me, whether true or not, that the author had taken some tricks on "how to write a novel" and gone just a little too far with them.
In particular, there were a few sentiments that were repeated in *over*-abundance. There really was no need to "repeatedly repeat" the "if only!!" thoughts of the main character. Also, the stories of romance between the main characters and their ladies were a bit cliched. You know, the better-than-average, yet romantically-inexperienced guy with the so-beautiful-she-turns-everyone's-heads, brilliant lady. And this line appears not once, but twice in this novel!
All that being said, I would still recommend to anyone looking for a good conspiracy-theory thriller about those little gray guys coming to take over the world.
THREE AND A HALF of five stars.
