The book tells the story of a man-eating Amur (Siberian) Tiger. But the book is not only solely based on this storyline, the actual stories of the tiger incidents are only a small portion of the book - the book also offers insight as to how people live with tigers in the taiga areas where humans and Amur (Siberian) tigers overlap. There is also fascinating insight as to how people think about these tigers - resulting in statements of their behaviour which are a bit hard to believe but apparently true (?) - the word vengeance in the title is not just thrown in there casually! The book's storyline is also an insight into life after the fall of the soviet union in certain areas of Russia, and the difficulties of the people assigned to protect the tigers.
It was quite an interesting read, but I am still grappling a little with the veracity of some of the stories about tigers, especially the attribution of emotions such as vengeance. Most probably it might be the case that the book is very much concentrated on the local opinions and thoughts about the tigers, but it does make you wonder whether these particular tigers can indeed be a bit vengeful.
