Gem does not remember setting out on the run. She only knows she is on the job, traversing the backwoods of the American West alongside her navigator, Banks. Her role is to drive. His is to manage the Seeker, the onboard machine tasked with overseeing their progress. Banks says Gem hit her head, but that hardly explains her condition. It feels like something is off, with her, with him, with the Seeker-with everything. When a calamitous chain of events in the town of Hawks Pass confirms her suspicions, Gem knows she can no longer trust the machine, though she has no choice but to carry on. In her line of work, disobeying directives has consequences.
