The Rumpelstiltskin Problem by Vivian Vande Velde
What's wrong with this story:
A father tells the authorities his daughter can do impossible things AND the authorities believe him.
A soon-to-be bride promises to give her future baby away to a TROLL.
Said bride agrees to marry the man who's threatened to kill her if she can't keep doing the impossible.
What would a troll do with a baby anyhow, and why would he give her all that spun gold for a tiny ring?
Why doesn't the heroine do ANYTHING to get herself out of this predicament?!
