Since I have stated my favourite playlist, I also want to state my favourite books from 2007. It's hard to decide but:
Neal Stephenson - "Snow crash"
I read this book several years ago, but decided to reread it after I found it in a second hand bookstore and especially because I only remembered that I really liked it but couldn't remember the plot.
George Orwell - "Down and out in Paris and London" I read this (together with his book about the Spanish civil war) during my trip to Bosnia and it is absolutely worth reading. He describes his contact with poverty in a honest but also humorous way. Somehow it gave me strength while I was traveling alone in Bosnia.
The books from Béla Hamvas.
