Rarity from the Hollow / Robert Eggleton,

Lacy Dawn's father relives the never ending Gulf War, her mother's teeth are rotting out, and her best friend gets murdered by the meanest daddy on Earth. Life in the hollow is hard. She has one advantage - an android was inserted into her life and is working with her to cure her parents. He wants something in exchange. It's up to her to save the Universe. Lacy Dawn doesn't mind saving the universe, but her family and friends come first.
