I won’t quote a single sentence of Timur Vermes’ “Er ist wieder da” (He’s back), because you really must read it by yourself. It’s totally hilarious! Very sarcastic, sometimes true, and even a bit real. I’ve read it in a few weeks, which means a lot (books with this size usually scare me and e.g. the Medicus took me four years to finish). ;-)
I would say, winter is coming, so get this book, a nice cup of tea and make it yourself comfy on your couch!
PS: Here are some other book recommendations.
