About the author
Tracy Diane was born and raised in Princeton, West Virginia. She grew up swimming and playing in the band. It wasn't until her twenties that she realized how much she loved a good story. Tracy attended Furman University planning to be a business major. Since Furman is a liberal arts school she had to take science and chose two geology classes during her freshman year, which changed her path. After receiving a Bachelor of Science in geology from Furman she went on to receive a Master of Science degree in geology at the University of South Carolina.
Tracy worked as an environmental consultant for many years, and then she took her love of rocks and minerals and turned it into a small business. Mini Me Geology's line of rocks, minerals, and fossils keep her busy when she is not writing her new Crystal Cave Adventures series. Tracy lives in Mount Pleasant, South Carolina with her two kids, their very large Great Pyrenees, Brutus, and cute cat, Brooks.
