Don Tillotson of Garden Valley built a dream home in El Dorado County with his late wife, Carol, as they raised four sons. As she was dying of breast cancer, she asked her husband to promote her self-published romantic thriller, "The Legend of Round Valley."He promised her. Before Carol Tillotson died of breast cancer in July, she made her husband agree to promote the book she'd spent the last year of her life polishing and rewriting. "She made me promise to push her book," said Don Tillotson, 72.
