So many SPOILERS ahead: 
 I read the start of this book, 554 pages, 72% of the massive book in one day. Can you believe it? Well, yes, because the start and most of the middle was amazing. I loved it. However, as the story progresses, as we enter the honeymoon, I start losing interest. First part, I liked because we get to know the characters, how they live pre-war and how innocent Tatiana is. I enjoyed it, and I was intrigued on how things progressed. The fact that Alexander was going out with Dasha took me by surprise and I (like Alex and Tania, I think) enjoyed the we-love-secretly-but-we-can't. Now in retrospective, I find it kind of absurd. Hell, Alex is SO GOOD that he does things really, really bad, like cheating. Trust me, Alex and Tania, Dasha would get over him. Dragging it, prolonging the secrecy was just messing everything up, and it would have been extremely easy if they would have said it from the start. 
 Then Leningrad. Having studies the Soviet Union I liked the setting and the war. But I think I wanted more. Suddenly, people starting dying so fast. And I don't understand why Tatiana, who was always giving and giving (making me get on my nerves, as Alexander) didn't die. Everyone seemed to be eating the most, I get why Marina died (who ate the glue on the wallpapers. I think this was my favorite morbid detail during the blockade), but everyone else just ate the double of Tania and didn't use as much energy as her. Plus, shells seem to repel from her. 
 Then we go to Lazerevo and we get the so wanted sex scene.... And another, and yet another, and more, more. I became tired. It was idyllic and boring, and all I wanted was to go back to Leningrad. Alexander becomes so possessive and authoritative that I disliked him. Here he had no justification for the way he was treating Tania, not like during the blockade back in Leningrad, when she was acting as if she had a death-wish, and I was with the old ladies. Yes, when they were eating altogether, he looked like an abusive husband and if I had been there (or at least at this time) I would report them to the police. 
 Then we go back to Leningrad (finally), and I am thinking: 'Oh, is she stupid?'. It's war. And it drags on until we get out of the USSR. 
 Didn't like the ending, too cliche, leaving me unsatisfied. Don't think I want to read the rest of the trilogy. 
 Last thought! 
 I may admit that the scene when she was at the hospital, with her healing ribs, and Alexander comes to visit her drunk, was too hot to handle.
