The Tiger by John Vaillant was a really good work of non-fiction about a man-eating Amur (Siberian) tiger in the Bikin River Valley in Far Eastern Russia in the Winter of 1997.
The book was just as much about the region as about the tiger itself and it was fascinating reading how many in the area forced to scratch out an existence living off the deep forest or taiga, with the effects of perestroika and it's freedoms not helping them at all.
In relation to tigers, Vaillant describes well the relationships between people and the animals and how they can co-exist, but also how the actions of people often throw that relationship out of balance.
It was an excellent book and more about it can be found in a New York Times review by Edward Lewine.
