Hero

"She's a waitress. He's a chef. They used to be best friends, but now, they're in love. She's also a selkie, a siren, Odysseus, Persephone, Helen of Troy, a Tudor queen, and a cowgirl called Quick Fingers. He's a really good man. When he asks her to marry him, Hero panics. She may be a lot of things but the one thing she doesn't want to be is anybody's wife. He gives her one week to decide, so to gather her thoughts, she begins to write him a letter.
