Overall a very good introduction to the history the Kievan Rus'—and indeed, the standard history thereof since its first publication way back in the 1940s. A bit dry in places, but it contains a real wealth of information presented in a narrative that for whatever it lacks at times in compelling intrigue does provide the core details of a dazzling array of plots, bitter fights for power, and other drama of princes and their factions who are fighting for the control of a growing domain. This book also however presents a decent amount of information on daily life: agriculture, religion and the like. It would be possible to read about three books in Russian and get the same information but also a bit more and with greater diversity of viewpoint as the Vernadsky book is a single-author volume, but for an English-language introduction to the Kievan Rus', this can't be beat, really.
