The Master And Margarita
The Master And Margarita -- Book Of The Day
I guess it's not really book of the day, since Bulgakov's The Master and Margarita is technically a story, but it'll do for our purposes.
I'm sorry to have another non-English book of the day, but I've been on a kick lately. I think it helps me speak Russian better. I love comparing translations, so give the English a read and let me know what you think.
I guess it can be classified as political satire, fantasy, fiction. There really is no way to define this genre. Bulgakov is brilliantly funny and sarcastic. And as is the case with my favourite books, not a word is wasted. There's no filler, everything is vital to the unfolding of this amazing satire.
Without giving it away, the devil comes to atheist, communist Russia. Unfortunately, there is no english word for the Russian 'smeh i greh,' it's basically when you laugh at something you know you shouldn't. And I've been doing a lot of that as I re-read this, laughing while shaking my head.
