This book doesn't require a suspension of disbelief, it requires that your disbelief be lobotomized.
The author tries to link a series of events that occurred in 1938 to a present day kidnapping, multiple murder, and bombing. An interesting notion that might have been plausible in more capable hands but here it just doesn't work.
Without giving away a key plot device, I'd note that the typical background check, even for a Top Secret security clearance, wouldn't delve into your genealogy and it is unlikely that your employer will tell you about your own past of which you are ignorant when 1) you're adopted, 2) from another country, and 3) when your last name is utterly mundane.
The hero of this story is angst ridden over the loss of his wife. We don't quite know why or how she died, I guess this is a teaser to get us to read the previous novels in this series, or why this matters.
The dialog is clunky and contrived. The characters are cardboard cutouts except when they act out of character -- in this book you will meet the only ex-drug dealer hit man in New Jersey who registers his firearm under his real name and address.
The unbelievable storyline and uninteresting characters are compounded by the author's unfamiliarity with his material. For instance, the recoil from a 9mm handgun will not knock down a 13 year old kid, when an airbag deploys upon impact it immediately deflates, ammonium nitrate doesn't explode - it is an ingredient in making a type of explosive, and on and on.
On the whole, Mr. White could have used a much stronger editor. If you feel compelled to read the book, check it out from your library.
