THE EXPANSE is one of the best series currently out there. It's also a series which has had its ups and downs. Some of them I've given 3 stars and others I've given 5 stars. I've always come back to it, though. Here, PERSEPOLIS RISING is setting the stage for the end of the line as we time skip 30 years to when our heroes are now in their 60s. They don't act like they are sixty so maybe it's a case of "sixty is the new thirty" thanks to advanced medical technology of the future but they do creak a bit more.
