Tenar in Tehanu by Ursula K Le GuinRead about the other entries on the list.
To my mind, Le Guin’s dazzling Earthsea Quartet ought to hold the place in our cultural esteem that Harry Potter and the etc does. We meet Tenar in the second book of the series, The Tombs of Atuan, when she is taken to serve as a child priestess to the mysterious Nameless Ones. But it is in Tehanu – older, wiser, and desperate to protect Therru, a child who has fallen under her guardianship – that she comes into her own. As a semi-literate middle-aged woman, Tenar is far from the typical fantasy heroine. But her fearlessness and grit as she works to build a life for the child she loves is as thrilling as any of Sparrowhawk’s dragon battles. Most daringly, on Le Guin’s part, Tenar’s perspective serves to interrogate the sexual politics of the earlier Quartet, and the fantasy genre in general.
