It’s not easy to findfantasybook series that are perfect from start to finish, so it’s impressive when an author manages to pen one of them — and it’s especially noteworthy when they manage to write two. Crafting a full series that doesn’t suffer from a slow beginning, sophomore slump, or disappointing ending is no easy feat.

This is doubly true for fantasy series and individual novels, both of which tend to be on the lengthy side. It takes true talent to ensure that readers remain engaged throughout such a story, especially if the narrative has many running threads and character arcs.10/10 fantasy book series might be rare, butthere are a few writers who are attached to more than one.

7Brandon Sanderson

Mistborn & The Stormlight Archive

AlthoughSanderson never quite topsThe Final Empire— at least, not in my opinion —The Well of AscensionandThe Hero of Agescome pretty close. Neither has many flaws to dwell on, as Sanderson masterfully crafts his story, magic system, and characters. The magic system is particularly impressive, but the characters' growth throughout the series is also a highlight.

The Stormlight Archiveis even more beloved among Sanderson fans, and the first arc of the series is also pretty much flawless.Wind and Truth’s endingbrings it to a satisfying close, reminding readers thatSanderson isn’t one to disappoint. It won’t be a surprise if he churns out a few more 10/10 series in the future.
