I had heard about this book for a long time, but didn't have any idea of how it was. I was very surprised - after a few pages, when someone's head is chopped off by a tram car, it's just like embarking on a rollercoaster of a surrealistic absurd. The writing is light, funny and witty, and it reminded me of other fantastic novels, like Manuscript found at Zaragoza. There is a background of social critic of the Soviet society and the absurd of burocracy, but always subtle and intelligent. A nice surpise.
