...but quite fun to read. Although I am sure most people, including Mr. Woods himself, are tired of this comparison, this book is very Clancy-ish in its Russia vs. U.S. one-upmanship and its submarine and weaponry technological detail work.
The story is told from two alternating viewpoints: the first from CIA department head Katherine Rule who thinks she has discovered a plot in which Russia will be invading Sweden. Not one of her superiors believes her and she must go behind their backs to continue investigating this dire possibility. The other viewpoint is that of a Russian submarine commander, moved from his normal naval command to an elite Russian fighting force, the one being trained for the invasion itself.
The storytelling is competent and not as technologically detailed as a Tom Clancy, making the story, in my opinion, flow more smoothly than Clancy's. I had figured out who the mole in the CIA book was long before the end of the book but it held my interest enough to want to find out how & when Katherine would discover it.
All in all, a nice earlier book by Woods and a step above most of his somewhat cookie-cutter mystery thrillers.
