Very disappointing.Writing a book about a popular character in a setting 20-years ago, a writer can make them look omniscient. Examples in this book: Having invested in Starbucks, the Japanese ecomonmy is riding for a fall, the Soviet economy is very shaky (and even the internal reports gloss over the problems) - all these in the very early part of the book. In this book, even Jack's inward thoughts are almost completely error free. This happened in other Jack Ryan books, but not in this concentration.And then, as it becomes clear how little is actually going to happen in this entire 618-page tome, the shock sets in: That's all there is?Few plot threads, mostly uninteresting characters. I hope the next one is better.....
