I saw this at a book store and it looked interesting—The Year of the Hare by Arto Paasilinna— found a some positive coverage. The novel was originally published in 1975 in Finland (Jäniksen vuosi).
About the story:
Vatanen, the journalist is feeling burned out and sick of the city. One summer evening while on assignment his car hits a young hare on a country road. Vatanen leaves the car to save the injured creature. This small incident becomes a turning point in Vatanen's life as he decides to break free from the world's constraints. He quits his job, leaves his wife, sells his possessions to travel the Finnish wilds with his new found friend. Their adventures take in forest fires, pagan sacrifices, military war games, killer bears and much more.
