^Oh, wow! You must be very proud of your grandfather! I hope he survived the war. The author's name is not William Craig. Sucks that I can't remember it because it's extremely well-written and a fairly new book containing a lot of info from the Russian side.
I googled it and I'm 99% it's Antony Beevor

Truly a fascinating read.
I was saying to the boyfriend that it's fascinating to me also because I'm not sure how it ends and he yelled at me "For fuck's sake, woman, do you speak German now?"
About Cernobyl, I remember it even though down here in Greece we ddin't have serious problems, or anything. I saw that documentary on Greek tv but I think it was a BBC documentary. I agree about the liquidators, I can't imagine the kind of courage it takes to fly a plane over the burning building knowing that this will kill you.
