The subtitle is Two Cold Wars and a Thirty-Year Journey Through Romania and Beyond and the author is Robert Kaplan (2016).
It is very much a travelogue and trip down memory lane for the author, who first visited Romania (and surrounding countries) in the midst of the Cold War. His visit again in 2013 and 2014, as the situation in Ukraine was heating up, confirming the existence of an ongoing dispute between East and West that did not truly dissipate just because the Berlin Wall came down. This region is simply the center point for that tug of war.
