One of my favorite books as a kid was a novel called The Ordinary Princess by M.M. Kaye. It was sort of a spin on Sleeping Beauty, only instead of a royal baby being cursed with an eventual long nap, The Ordinary Princess was about a princess who, unlike her older, blonde, more beautiful siblings, receives the "gift" of being "ordinary." That means "mousy" brown hair, freckles, and a disinterest in silky princess dresses. She's pretty much the family embarrassment, so eventually the princess moves out of her castle, gets a job as a maid in another castle, meets a prince who’s also pretending not to be a royalty, and they fall in love and get married, etc. (I swear I’m going somewhere with this, so stay with me.)
