The book is full of inaccuracies concerning military hardware and tactics. From Black Hawk helicopter with skids, (they have wheels), to sudden promotions of rank from Master Sergeant to Captain and then back to Master Sergeant, all within the same fire fight, a mission briefing for a super secret military unit in a partially remodeled warehouse instead of a secured military facility. Come on! I find these inaccuracies reduce the creditability of the writer and thus the story. The book does not provide the reader any real depth into the advance technologies that the Ghost could use. You could learn more from a good episode of Future Weapons.
Spotty character development, sci-fi weapons, lots of talk about honor and commitment (that works until it gets too syrupy towards the end). All of the good guys have big square jaws (or are pretty tomboys) and have wonderful biographies - a walking recruiting poster. The bad guys carry fetish swords and use prostitutes and plan to hijack China's foreign policy as part of their ill-defined personal vendettas.
One thing the reader may find annoying is the shameless and sort of funny Blackhawk tactical knife advertisements scattered throughout the book. I'm not talking about just one or two lines, these things go on and on. Here's an example;
"Brown unsheathed his Blackhawk Masters of Defense Nightwing and took it into his left hand in a reverse grip. He wasn't expecting to use it, but you never knew. The fixed blade had a fiberglass nylon handle with wing-walk inserts, a black tungsten diamondlike carbon (DLC) finish, and a serrated spine, giving him a secondary edge for back cuts and draw cuts. The blade was 5.9 inches of pure death, and he considered it the American Express Card of knives- because he never deployed without it."
This chestnut is truly gruesome, especially that Schwarzeneggar one liner at the end. Thankfully these deviations from the course of the story are not frequent and I think we should refrain from blaming the writer for them.
It has the same problems as books based on movies or TV series, how to make the extremely visual work in a non-visual format, and everyone seems to use the same ideas; extreme detail about any weapons used ... no one ever just draws his gun but draws his 1923 Match Grade Browning Designed High Power with the special 5.75 inch barrel with super duper rifling for additional spin and accuracy with the super new titanium shelled yadda yadda yadda at the same time as his enemy draws his yadda yadda yadda gun; action scenes resemble old Batman movies (OK, so it's not quite that bad), and the amount of time spent on character development (the usual sign of a decent or above series) is minimal ... this one is only for the terminally addicted to this format, usually a young adult male; if you need to read Clancy look somewhere else in his bibliography, even some of his non-fiction is good.
