What is "tehanu"

Tehanu: The Last Book of Earthsea is a fantasy novel by the American author Ursula K. Le Guin, published by Atheneum in 1990. It was the fourth novel set in the fictional archipelago Earthsea; a sequel following almost twenty years after the Earthsea trilogy (1968–1972); and not the last, despite its subtitle. It won the annual Nebula Award for Best Novel and the Locus Award for Best Fantasy Novel.

Tehanu continues the stories of Tenar, the heroine of the second book of the Earthsea series The Tombs of Atuan, and Ged, the hero of the first book, A Wizard of Earthsea.
