Crystal's Solid Gold Discovery - Paperback

When Crystal Blake discovers a deserted gold mine in the mountains of Idaho, she decides to explore it. But if it's deserted, why is there a helicopter landing pad beside it? And why is smoke coming from the smokestack? Maybe Crystal's plan of a quiet week of vacation in rural Idaho, learning to ride her new horse, and getting to know handsome Shawn Sorensen better, won't happen quite like she expected. Meanwhile, she discovers a burlap bag buried in the middle of a field. When she carefully cuts into it, not sure what she'll find inside, she realizes It's not squishy at all. What spills out is heavy, metal, very old, and very broken. She and her dad try to solve the mystery as she wonders what is happening with Shawn.
