Jump

During a nuclear war, the government moved all of it's eligible citizens to floating landmasses known as "Rims" Clara lives on a Rim with her smuggled dog, Alaska, named after the state she hovers above. Every single day she stares down at the quite, abandoned wilderness below her. She can't jump, 1. Because there is just an empty world below her, and she would surely die, and 2. Because if she jumped, she would fall to the ground, and die. But maybe, just maybe, she could get down, but how could she get back up? No, there was no way she was getting off of that island.
