Ursula K. Le Guin [SEP] Later writings
Other works from this period included "Lavinia" (2008), based on a character from Virgil's "Aeneid", and the "Annals of the Western Shore" trilogy, consisting of "Gifts" (2004), "Voices" (2006), and "Powers" (2007). Although "Annals of the Western Shore" was written for an adolescent audience, the third volume, "Powers", received the Nebula Award for Best Novel in 2009. In her final years, Le Guin largely turned away from fiction, and produced a number of essays, poems, and some translation. Her final publications included the non-fiction collections "Dreams Must Explain Themselves" and "Ursula K Le Guin: Conversations on Writing", and the poetry volume "So Far So Good: Final Poems 2014–2018", all of which were released after her death.
