The Quantum Thief is Hannu Rajaniemi's debut sci-fi novel, and the first of a planned trilogy. In a post-Singularity solar system slowly being eaten by a community of uploaded minds, Mars has remained independent and unique thanks to its extreme attitude to privacy: all memory is externally stored and encrypted, and you can't access a memory unless everyone involved consents. This makes life pretty difficult for detective Isidore Beautrelet, but as a native Martian he wouldn't have it any other way.
