A novel by Rory Harper
This critically-acclaimed science fiction novel is set in an alternate universe in which organic, semi-sentient, alien-engineered oilfield drilling rigs roam the plains of Texas and the Southwest in search of petroleum. Petrogypsies is the first in Rory Harper's series about the great drilling beast, Sprocket, his best friend, former farmer Henry Lee MacFarland, and the rowdy, musical crew of "petrogypsies" who travel with them in their quest for fortune, romance, and adventure.
