The 51 Best Fantasy Series Ever WrittenThe Mists of Avalon and its decades-spanning series of sequels and prequels all tell the familiar tale of the Arthurian legend, but with characters such as King Arthur and the Knights of the Round Table playing secondary roles. Instead, the series follows the lives of the women in Arthur’s court, and explores the Matter of Britain from a more feminist perspective.
The Girl of Fire and Thorns series by Rae Carson. Don't let this pic fool you, it's a trilogy, the three on the bottom are just novella's. I am in LOVE with this series!!!! One of the best fantasy series I have read in a long time, absolutely amazing!!!!
