While it’s quite exciting thatThe Expanse’s successor is (hopefully) coming soon to Amazon Prime Video,the bad news is that the upcoming TV show has a tough road ahead in one specific regard.It has been a long three years since the popular sci-fi TV series ended. Since then, many have championed a season 7 renewal, whether on Prime Video or another streaming service/network. Unfortunately, there have beenno updates concerningThe Expanseseason 7, but its perfect replacement is in the works for Prime Video.

PerVariety,Prime Video has greenlit an adaptation of James S.A. Corey’s trilogy,The Captive’s War.The first book in the series,The Mercy of Gods, was published in August 2024, and the other two are forthcoming. Corey (a pen name for Daniel Abraham and Ty Franck) is the same author behindThe Expanse, and like the former show, the writers are working on the upcoming TV adaptation of their trilogy. Additionally,The Expanse’s showrunner Naren Shankar is executive producingThe Captive’s Warand serves as its showrunner. So, it’s easy to see howThe Captive’s WarisThe Expanse’s successor.

So, it would be impossible to adapt the book’s story without showing much of the Carryx as they are the rulers of this fictional sci-fi universe.

One of the trickiest parts of making a sci-fi movie or TV show is generating unique alien races that are believable to the audience.The Expansesteered clear of this challenge with ease.
