For those who are not familiar with the genre, immersion can be difficult because it is a futuristic and psychedelic world (because of the virtual and pervasive drug). The plot is fairly linear as it does not involve the different usual powers of such groups (mafia, multinational corporations, governments, ...) from some time keys in times such as Turing inspection body. This is why I would say this book is quite easy to read for a neophyte if he does not get lost in the psychedelic meanderings of the story's protagonists. Finally, the story leads us to reflect on the nature that could take an artificial intelligence. Personally, I did not bored for a second!
