For anthropology graduate student Sam Delgado, his appointment as crew chief for a university archaeological field school was his last chance to salvage his PhD. But when the collapse of American banking and credit leave him and the rest of the students trapped in the Wyoming high country, his entire world vanishes overnight.
He, and the rest of the students, must adapt to this strange new world where travel is banned, money is worthless, and even communication with home has gone deathly silent. Sam finds himself dependent on the good will a Wyoming ranching family, a rugged archaeology professor, and an aging Shoshoni medicine elder. Just as all the cards seem to fall his way, a ruthless predator takes control of the Big Horn Basin, and Sam's life is looted of all that he loved. Now, as Wyoming struggles to survive, he and the outcast Breeze Tappan will place their lives on the line in an attempt to save just a little of their world. And in the end, Sam's only ally turns out to be a mystical Shoshoni Spirit Helper called Nynymbi.
