Is there anything better than a book series that has you immediately reaching for the next book and feeling devastated when it’s over? The best book series of all time deliver.

Following these characters over the course of several novels, sometimes for generations, can make readers feel like they are part of the family. Adventure stories take you along on an invisible participant in the group’s quest.

Sometimes a series can take you to completely different worlds or one that feels slightly familiar. Other series may involve time travel or other galaxies. But wherever these books take you, you are sure to have a good time! And in the course of literary history, a popular series can even open up new opportunities for writers in different genres, inspiring generations of authors to come and expanding the number of stories published.

Just a few notes on the list: when choosing the series for this list, I didn’t include any children’s or young adult series, which typically make up a lot of the “best series ever” lists. And while we love those types of series too, this list just includes books written for adults, both finished and unfinished series. Okay, what are we waiting for? Let’s jump into the books!
