Alice stabbed the Emergency Descent button and held onto the armrest as the car fell to the ground. She hadn’t cleared the park; a wide green lawn raced up toward her. Thirty feet from impact, the engines spun up, and the Hopper thundered to a halt; a gale outside but the park remained immaculate, unmoving. She forced the door up with her shoulder and slumped out to fall on the lawn. The grass was brittle and stiff, each blade pricking her skin as if she were rolling on a hard brush. She tried to sit, only to slump to her side.
