Karinne's been engaged to Max for two years, but everything conspires to keep them from actually getting married. His job as a guide in the Grand Canyon. Her job as a Phoenix-based sports photographer. Her family's troubled past. And now, making matters even more complicated, Karinne has reason to believe that her mother—long presumed dead—might be alive, after all.

Now Karinne and Max are spending a week in the Grand Canyon on a rafting trip. It's supposed to be a pre-wedding vacation, a chance to enjoy some time together, an adventure. But it could be a little too much adventure. Especially when Karinne's mother, Margot, shows up—with a shocking request. It's another thing that comes between Max and Karinne. They love each other, but that might not be enough for this reluctant bride to walk down the aisle!
