After her interesting exploration of life in East Germany during the communist era, Stasiland, I ordered this with keen anticipation. However, whereas that piece was compulsive reading, I found Funder's novel a rather leaden encounter which required determination to read. (In fact, on reflection, Stasiland was not brilliantly written, but the stories assembled were what made it so gripping.Perhaps this is the key to my disappointment.)
The structural device of multiple voices and time periods demands much more careful and deft handling than I found here. As others have commented elsewhere at some length, these voices are insufficiently differentiated for a) narrative clarity and b) character development, to provide the hook which prompts enthusiastic engagement. I should add, 'for me', of course. I have to admit I gave up after about 100 pages. To be frank, the 3* is in recognition that it's unfair to damn a book one hasn't finished: were I actually rating my own enjoyment of the book I would be a little less generous.
