Eve Swango and Tommy Baca belong to each other. Always have. Always will. It's been years since Eve followed Tommy into the wild, subterranean depths of a New Mexico cave. Years since she realized they shared the same passionate soul, the same curiosity about that hidden world below. Tommy, intense, beautiful-hers-became her past, her present and her future. But something within Eve won't allow her to marry Tommy, no matter how often he asks. No matter how deeply they love... As the years surrender to time, Tommy and Eve move in and out of each other's lives, finding joy and sadness in equal measure. Each must learn, does learn, that love comes in many guises-and in the end it's the only thing that counts.
