Δαφνη Ευτυχια Αρθουρος

From The Grimm Legacy by Polly Shulman (via Goodreads):

"What are you doing?"

"I'm darning a sock," he said, holding it up to show me.

"What's that lump inside?"

"A sock egg."

"A sock egg? I didn't know socks hatched from eggs."

"Only the best ones do. I can't wear the cheap kind, the ones that grow on trees. They give me blisters."
