I just read this and wanted to recommend it as it is really really good. I have read others of her books and this is one of the best - couldnt wait to go to bed so I could read!
Centres on a young woman and her family during the seige of leningrad by the germans during the second world war. If you like a gripping story it takes a little while to get going while the characters are developed, but it is worth it.
The writing is fantastic, and the attention to detail in building up atmosphere, character and setting is what makes it.
