Two Moons, Three Suns

The Moon and the Sun is a novel by American writer Vonda N. McIntyre, published in 1997. The book combines two major genres: science fiction (specifically the alternate history subgenre) and historical romance. It won the Nebula Award for Best Novel in 1997, beating out A Game of Thrones by George R. R. Martin. The novel was inspired by the short story (written in the form of a faux-encyclopedia article) "The Natural History and Extinction of the People of the Sea", also by McIntyre, which was illustrated by fellow author Ursula K. Le Guin. The novel was re-released as The King’s Daughter in 2021 as a tie-in with the film of that name based on the book.
