Anthropologist Dr. Silver Collins is used to laughter, derision, or fanaticism when she tells someone she's an ancient astronaut theorist. So when she receives none of those reactions from cowboy Layne Dawson, she's intrigued. What also intrigues her is that the man has lived in the same town all his life, is amazingly confident, and is absolutely content with his life. His main goal appears to be to keep everything just the way it is.
Layne, a confirmed bachelor, has never met a woman like Silver, and it's not just because her hair is completely white at the age of thirty-four. She's traveled the world, quenching her thirst for knowledge about ancient cultures, determined to make a discovery that will help mankind understand its past. Her sacrifice and drive to reach that goal is something he's never known and he finds it, and her, riveting.
The more Silver learns about Layne, the more she appreciates him. When it looks like his help could be instrumental in reaching her life-long goal, her respect and gratefulness turn to something more. But when it becomes clear that her life is as alien to him as his is to her, she has to admit they truly are worlds apart. The chances they can bridge the gap are about as low as the chances aliens visited Earth in the past...or did they?
