They left the motorcycles off and continued on foot. After nightfall, currents beneath the sand kept shifting, and the tires could easily sink into loose sand. Even with the weighted armor on his back, Ryan's steps were firm, grains crunching beneath his feet. Mo Lei matched his pace, her breathing steady.
