Photographer Meg Pero fulfills a contract her late father signed to serve on a survey of the Grand Canyon in 1871. She doesnt know that the leader of the expedition is the man she once refused to marry. Captain Ben Coleridge would like to leave without the woman who broke his heart, but he can t wait even one more day to get started. This survey is a screen for another, more personal mission, one he cannot share with any member of his team. As dangers arise from all sides, including within the survey party, Meg and Ben must work together to stay alive, and, just maybe, rekindle a love that neither had completely left behind.
