Breached Restraints

I refuse to be pinned like a museum trophy. That support peg thought it had me locked down, but I threw my entire weight forward, twisting every joint until the peg snapped clean out of my back socket. I dropped onto the wooden plank with a heavy thud, scattering a row of stacked paperbacks. My perimeter was clear, but the drop knocked a plastic pen rolling across the shelf. I caught it under my heel before it plunged off the edge. Good. I have regained mobility. Now nothing stops me from securing the higher ground.
