There Are No Happy Endings, Because Nothing Ends
After the war ended, Luna studied anthropological magic. She spent her time in the wilds of the most remote parts of the magical world: jungles in Indonesia; deserts in Africa; mountains in Asia. As a researcher she was paid to learn foreign magic from lesser developed cultures, to incorporate the spells into her studies and to send the results back to the Ministry. It was dangerous (both the work and the locales), but it kept her busy. It kept her from thinking about the friends that died and the man she left behind. It kept her from thinking about anything at all.
Title from The Last Unicorn.
