A book written in 2010 mentioning the Internet is always a bit sad: the hopes were high. The Internet is not the main topic, but it's there, along with other social spaces visited by the two main characters (a bad private detective and an excellent one hired by rich people to find a troubled teen). Despite being opposites, the two PDs share the same social expertise, as well as most of the other characters.

It never stops feeling like a writing mistake, a narrator bleeding all over the characters, drowning their voices. Yet, I suspect this is what people like in Despentes' fictions (it was the same in the Vernon Subutex trilogy): she is clever, she knows how to read the various social strata and their logic; she is also enraged and cannot engage with the world without brutally bringing back everyone to their mediocrity. Despite that, her characterization fails to elevate above a smart use of categories, all very finely defined, but never coming close to reality. No character seems plausible, because they are all animated by the narrator-author's rage and driven by her bleak outlook.

So, it's probably a good read if you want to cultivate your contempt - everyone is guilty of mediocrity in there (except maybe the hedonist). The point is destruction (the book is labeled "punk" and allows everyone to conveniently forget punk used to also mean "DIY").
