Jack and Diane. Two names joined in the common parlance by a pop song. They are also the aliases of two people whose real names--Adam and Eve--are no less joined in the common parlance, and represent the divine calling they share--a calling to show humanity the way back to the garden of Eden. Neither knows the other exists until their travels lead them to the same town. It is there that their mission begins--a mission that unleashes terrors, teaches lessons, and yields the answers they hope will lead a world blinded by guilt, fear, and hatred, into a place more closely resembling the state of man's original perfection.
