Star Shapes in Bloomington, MN

Kidnapped from downtown Birmingham, Alabama, and taken to the country, our protagonist is pretty irked.
Rather than ask for a ransom, her captors make her feed animals and read dusty books.
She is unnerved by the growing realization that something weirder is afoot, and it all ties back to a book of strange constellations known simply as Star Shapes.
People look to the stars to read the future, but sometimes the stars conceal stories from the past.
