Thin Air feels like a Takeshi Kovacs knock-off but given that it's written by the same author, I guess that's ok. Just like Altered Carbon, Thin Air is about a ridiculously overpowered ex-soldier trying to solve a crime in a cyberpunk city and ends up digging deeper and deeper into unraveling a conspiracy. But this time, it takes place on Mars.
To be fair, this is a totally different universe than the Takeshi Kovacs series and has its own unique new technologies. It actually takes place in the same universe as another of Morgan's books, Thirteen, but Thirteen takes place on Earth and Thin Air takes place on Mars so the only overlap is in the names of some governemnt organizations. But if you enjoyed Altered Carbon, I think you'll enjoy Thin Air. They both have a similar sci-fi hard-boiled detective noir feel.
Thanks, just in time - I was looking for my next read.
