The Last Hundred Days by Patrick McGuinness

In this book a young, British man who's recently lost his father (and his mother before that) finds himself in Bucharest, Romania, teaching at the University despite not having a bachelor's degree or even having interviewed for the position. While the first part of the book deals with his at-times naïve culture shock and his response to the Communist regime, as the story progresses, the narrator finds himself more and more deeply embroiled in the society and more and more called upon to react to the abuses of the regime. While this book is certainly about the end of the Ceauşescu regime, it's also about growing up and taking responsibility for your actions rather than drifting through life.
