This is disappointing to hear, but to anyone who is deterred by this comment from reading it in English, don't be. Even in English, the book was undoubtedly one of the best books I have ever read. There's something about it that makes you go "What happens next?!" for all 400 odd pages of it, and before you know it, you're at the end. It's truly a masterpiece - Bulgakov spent 10 years writing the final version of the novel after burning his initial manuscript twelve years prior in 1928, but as you will come to learn, manuscripts don't burn ;)
