For those interested in Russia and its past, this is not a bad place to start. It is as comprehensive as a 600 page volume can be. I read the Fourth Edition, so am glad to hear that it has been updated at least to the Gorbochov era. Riasanovsky is particularly adroit at representing early Russian history, with vivid accounts of the numerous invasions (Mongols, Vikings, Tatars, Teutons, etc.). After reading this book, one cannot help but understand the national paranoia and xenophobia that has been so much a part of Russian policy and posture throughout so much of its history. It also becomes clearer why Russia has historically needed a central "father" or "mother" figure to guide it through its tumultuous periods.
As to a reader's criticism, Riasanovsky is indeed somewhat biased, but certainly no more than the typical American historian writing about US History. He gives more than equal blame, for instance, to Nicholas II for getting his country involved in the Crimean War. He certainly never acts as an apologist for any of the Russian rulers at any stage, though his admiration for Peter the Great and Catherine can't be denied.
Poles, Ukranians, Lithuanians, etc. are not going to be won over by this book, but it is to the author's credit that the reader understands why they wont be. But winning anyone's approval is hardly Riasnovsky's object. He's primarily trying to tell the story of a people, and he succeeds on that level, quite brilliantly. The story he tells is complex and fascinating, to say the least. So many colorful and unforgettable characters advanced across Russia's historical stage, that any other country would be hard put to come up with such a cast or a saga.
