I loved revelation space! unfortunately, most of Alastair Reynolds audio books are narrated by by a voice actor who’s narration I personally find off-putting. I find him very affected and self absorbed, so much so that it distracts from the characters and story. it’s nice to actually stop and read though, just harder to find the time.
the Culture series by Iain Banks sucked me in completely! it starts with Consider Phlebas for anyone looking to jump in.
