Lee Jackson does get better and better. Full disclosure – I read book 4 before Book 3 because of which book was in my call bag going back and forth to the hospital. I do think that it is important to read the first book in the series in order to understand the back story of Atcho. But this book is also a great stand-alone thriller. Jackson does what is so important for any author writing historical fiction – the author has to weave his fiction into the real history of the time. Atcho and his band of “good guys and gals” are fighting a WMD terrorist against the backdrop of the opening of the Berlin Wall in 1989. And the evil-doers are definitely well qualified to defy Atcho – from influential Russian generals, to a rogue Stasi officer, and Chechen terrorists. Jackson has some new characters, with returning characters, good and bad, from Atcho books 1-3. The action moves very fast, and several plots are woven together at a break-neck pace. This is without question on one of THE BEST cold war spy thrillers I have read since some of my favorites by Sean Flannery (David Hagberg ), Back to work Jackson - - - I have no Atcho books left to read. I will catch back up with Tim Tigner and Jason Kasper on my bedside table.
