A story of miracles and visions in the fertile, endangered Rio Grande Valley.

Rosa Marquez and Sean Carpenter have two things in common: they're both native New Mexicans, and they're both seeing visions. Rosa encounters the mythical flute-playing hunchback Kokopelli on a hike in Albuquerque's Petroglyph National Monument. Sean sees the Virgin of Guadalupe in the dry, barren bed of the Santa Fe River.

Both give cryptic messages that lead Rosa and Sean to join a fight to save the dwindling Rio Grande, one of the country's most endangered rivers. It's a fight that leads them to tangle with a powerful developer who doesn't hesitate to play dirty, a fight that puts both of their lives—and their hearts—on the line.
