Rarity From the Hollow

'Lacy Dawn's father relives the Gulf War, her mother has lost her teeth, and her best friend is killed by her own father. Life in The Hollow in West Virginia isn't great. But Lacy Dawn has one advantage-she's been befrended by a semi-organic semi-robot (DotCom, alias Buddy) who works with her to 'cure' her parents. Buddy wants something in exchange, though. It's up to Lacy Dawn to save the universe.' -Books for a Buck
