For me, I maxed out all the Sci-Fi movies and TV shows out there and wanted more and discovered early on that Sci-Fi books are 1000 times better than whats out there in movie land. My problem is I have a hard time keeping track of where I am in all the book series I've been reading as new books sometimes take a year or more to come out depending on the authors.
I recently started the series and went with Redemption Ark as book 2 (according to Goodreads) Hope I'm not missing too much going with the Goodreads ordering :/
His take on this is: " The reading order isn’t that critical, in my view, but it probably improves things to read REVELATION SPACE, REDEMPTION ARK and ABSOLUTION GAP in that sequence. THE PREFECT (AURORA RISING) and ELYSIUM FIRE may be read alone or jointly, but should best be read in the above order. CHASM CITY, as well as the collections DIAMOND DOGS, TURQUOISE DAYS and GALACTIC NORTH, can be read at any point."
Yup, if you like scifi/fantasy movies consider that there are at most 2 or 3 that raise to the level of a mediocre sci fi book, and even those are book adaptations.
