There are dozens of science fiction books that can truly be considered exceptional. However, that number considerably shrinks when it comes to sci-fi series that can claim S-Tier status, with the condition that all of their installments are excellent reads, without a single bad book in the series. While good and bad are obviously very subjective terms, there are seven series that sci-fi fans, for the most part, can agree are without fault.
Screen Rant highlights seven series, but that doesn’t mean there aren’t more sci-fi series that, subjectively, don’t have a bad book. This list also doesn’t discount series that are technically ongoing; it does, in fact, consider and highlight series that aren’t complete yet.
So, if we didn’t include a sci-fi series that you think deserves to be on this list, then drop the name in the comments below. But without further ado, these are Screen Rant’s top choices for sci-fi series without a single bad book.

Red Rising by Pierce Brown
Published: 2014–present; Notable Subgenre(s): Space Opera / Dystopian
While there may be a few outlying naysayers, most sci-fi fans can agree that Pierce Brown’s Red Rising series is beyond epic and more than deserving of a spot on this list. The divide in opinion may stem from the fact that the series was originally a trilogy before expanding into three additional books, with a fourth on the way.
Some fans struggled with the transition from the original trilogy to its sequels, notably because of the expanded POVs, with the sequels following characters outside of Darrow. However, for those who could get past this hang-up, the series is a 10/10, with many fans desperate for Brown’s final book, Red God, to finally be released.
6
The Vorkosigan Saga by Lois McMaster Bujold
Published: 1986–2016; Notable Subgenre(s): Adventure / Comedy
Lois McMaster Bujold’s The Vorkosigan Saga truly deserves a standing ovation, with the series standing out thanks to its roughly 16 primary books when counting the main novels and novella-length works. The sheer size and unusual structure of this series make its claim to “no bad books” all the more impressive.
From military adventures to political intrigue to romance and comedy, this series truly has it all. If you haven’t read the series but love Star Wars, we highly recommend checking it out, as it brings the epic space battles and family drama that define Star Wars.
5
Wayfarers by Becky Chambers
Published: 2014–2021; Notable Subgenre(s): Hopepunk / Space Opera
If you’re more of a Star Trek fan than a Star Wars fan, then Becky Chambers’ Wayfarers series is a must-read. Like Star Trek, Wayfarers strongly emphasizes a multicultural interstellar civilization. Unlike Star Trek, though, Wayfarers focuses less on wars, major political conflicts, and constant crises and more on friendship, family, community, cultural differences, and what it means to coexist.
Made up of four books,The Long Way to a Small, Angry Planet (2014), A Closed and Common Orbit (2016), Record of a Spaceborn Few (2018), and The Galaxy and the Ground Within (2021), Wayfarers notably won the 2019 Hugo Award for Best Series.

The first book isAncilary Justice , followed by Ancillary Sword and Ancillary Mercy. All three books are highly acclaimed among readers and critics alike with Ancillary Justice notably winning Hugo , Nebula , Arthur C Clarke , BSFA , and Locus Awards.
