This book does a wonderful job telling the story of President Putin (with exceptional detail). To my knowledge it is the most intimate and comprehensive book on Putin that is available, outside of academic papers. The book is long, very long, which is necessary to convey a realistic image of this fascinating world leader.
Narration is totally fine, I felt that the pronunciations were clear and that the narrator spoke with a good mix of enthusiasm, interest and subtlety.
One challenge that stood out was the sheer number of names that one must remember throughout the course of the book (Russian names that most English speakers will not find easy to recall). But this is obviously unavoidable if one wants an accurate retelling of events.
Overall: Get this book if you want to learn about President Putin.
