I loved this book. Everyone has a different opinion on what the best translation is, so it’s worth briefly scanning a few different ones to see which you like best. I had a really hard time getting into the Ginsburg translation, but really enjoyed the Pevear/Volokhonsky one.

Also, this site: http://masterandmargarita.eu/en/ is a great resource if you’re not familiar with 1930s Soviet history and the Gospels (both canonical and apocryphal). Without knowledge of those things you won’t get nearly as much out of the book as you could.
