It's a long overdue book review, but I'll just write a few words about it.
Simply put, this is one of the best, if not the best Russian grammar books that I have ever read. It goes beyond conventional grammar and explains a number of exceptions that simply do not conform to the general rules. It is divided mostly by part-of-speech (Verbs, nouns..etc.) and covers a wide array of topics. It draws examples from famous literary works and news articles. The language is clear, concise and straight to the point. I cannot stress how valuable this book has been for me. It is truly the Holy Grail for any Russian language student. Five hundred pages of pure grammar (I'm a grammar junkie) is what will raise your command of the language from good to excellent.
I should point out, though, this book primarily targets intermediate and advanced students of the language. Also, this is a reference grammar book. Beginners might find it intimidating at first, but fear not! Once you have a solid grasp of the basic grammar, this book will help you expand on them. In addition, it does explain the basics, but in a far more detailed manner, so there is some review there if you're quite unsure about the basic rules you've learned.
But honestly, though, I cannot stress how important this book is. Even if you have a Ph.D. in Russian (I don't have one, unfortunately), it's still a valuable asset. It costed around 60 CAD, but it was worth every penny I spent.

I will write more book reviews, but right now, check this book out. You'll love it. (I can't believe I haven't written a review on it until now!)
