Lance Honeycutt lives at the edge of the Big Dry—an arid patch of land aching for water in a drought. To make matters worse, the well of love has been long dry for him, too. He hires a water witch to dowse his land. Rod Mascioli--who is just the right man to end both dry spells.

In comes Rod Mascioli—a man with a tool guaranteed to make things wet. A "water witch," Rod and his dowsing wand sleuth out hidden treasure in the desert—and burst the dam of self-isolation and loneliness in Lance's heart.

Following clues left behind centuries ago, Rod and Lance search for a fabled underground spring while heating things in the Big Dry.
