I grabbed this from a library discard pile, but the reason I picked this one up among the hundred or so there is my growing interest in Soviet dissidents. Reading the cover flap and a quick Internet search, I figured it was worth the time to read a medium size biography on Andrei Sakharov. I wouldn't turn someone away from this book, but I think I would rather have read the man's memoirs (the one not confiscated by the KGB). Sakharov has two main claims to fame: the inventor of the Soviet H-Bomb and as a dissident. This book is very thin on the former, which is a bit of a disappointment. Based on this, I'm really quite puzzled why he deserves that title. The biographer also skips over some apparently important points, such as why Grisha Umansky is so important.
The transformation from a shy intellectual to a constant thorn in the side of the KGB was much more interesting. Really, this would have been much better if it just dropped the first 50 years of Sakharov's life, gave a ten page introduction to the man, and then became a study in the various dissidents who flit in and out of the book. I would love to have seen a detailed comparison of Sakharov and Solzhenitsyn, who knew each other and had a different view of the world. This difference comes into and out of the picture too quickly to really make too much of it, as do a number of the dissidents (that said, if you do pick this up, keep a notecard of who those people are; they might be worth looking into).
Overall, I give it 3 of 5 stars. I wouldn't talk someone out of it (or any book highlighting the horrors of the "workers republic"), and I learned some from it, but I think there might be better works out there.
