This year's books:
1. Werner Munter 3x3 Lawinen (in German). A book on estimating the probability of an avalanche and how to reduce the avalanche risk while skiing)
2. Yanis Varoufakis, And the weak suffer what they must? (in English). A book on the recent/ongoing European economic crisis. Very eye-opening. It strengthened my pessimism on the topic, although the book itself ends in a rather optimistic tone. It confirmed my suspicion that the former greek finance minister was more of an academic and less of a competent politician.
3. Charles Bukowski, Post office. Finished it in a day. There are very few books that can be read so easily and be so multy faceted and insightful at the same time.
I would be inclined to vote for Post Office, but the book on avalanches is already proving itself quite useful...
