In the distant future most of the human race has fled a ravaged Earth to find new life on other planets. For those who stayed a lawless society remains. Technology has been renounced, and saints and sinners, lawmakers and sheriffs, travelers and gunslingers, abound. What passes for justice is presided over by the High Sheriff, and carried out by his cruel and ruthless Deputy. Then a ship falls from the sky, bringing the planet's first visitor in three hundred years. This Stranger is a crewmember on the first ship in centuries to attempt a return to Earth and save what's left. But her escape pod crashes hundreds of miles away from the rest of the wreckage. The Stranger finds herself adrift in a ravaged, unwelcoming landscape, full of people who hate and fear her space-born existence. Scared, alone, and armed, she embarks on a journey across the wasteland to return to her ship, her mission, and the woman she loves. Fusing the fire and brimstone of the American Old West with sprawling post-apocalyptic science fiction, Frontier is a heartfelt queer romance in a high noon standoff set against the backdrop of our planet's uncertain future.
