A very enjoyable and intriguing read, and very well translated from the German.
Each episode seems to be separate and different, but like a good detective story, it is fun making the links between them. The same character will pop up in a story about someone else. There are stories within stories, and pastiches of different narrative styles. The computer geek style in particular is great fun.
The theme is fame and its effects,and what happens to your sense of identity when you become famous, but also the impact of modern technology,and what happens when it goes wrong or is suddenly absent.
