When I was visiting
uniquecrash5 for Cheese Weasel day he loaned me a copy of Altered Carbon, a noir SF novel about body swapping, dysfunctional marriages and functional immortality.
The story follows an ex UN Envoy (i.e. shock trooper), Takeshi Kovacs, as he gets involved in investigating a suicide.
Of course, in this setting, the human consciousness can be backed up, so he's hired to investigate the suicide by the perpetrator/victim.
It's an interesting book. The narrator/protagonist comes across as just a little too competent, and the plot gets a bit too convoluted, but overall it's enjoyable if you're willing to invest into the story. And flip back a few times.
There were enough references to previously undisclosed facts that I kept wondering if this might be the second or third book in a series, but it is indeed the first. The story is definitely hard-boiled, with pheromone spewing femme fatales and cybered up mob torpedoes threatening our hero at every opportunity.
It does make me want to go back to the Chandler & Hammett books I have from my university English courses.
Oddly enough, I don't think it ever explains what the title alludes to, even though it mentions it on several occasions.
