She awoke with a jerk of all her muscles. The back of her head banged against metal and her right leg cramped so hard she groaned in pain.

“What the hell?” she whispered. It was so dark that she felt her face to see if she had a blindfold on, because she knew her eyes were definitely open. As she lay on her back in the pitch blackness, she became aware of sounds and smells. The first thing she noticed was the tang of fish in the air, and the cold metal underneath her body. This led to another realisation: She was naked. Her buttocks were numb from the icy metal and her back ached. She could feel little studs in the floor in a line heading off into the distance.
A low thrum could be heard and felt under her hands.
A ship then. Some sort of fishing ship? By the aching cold biting into her body, it was most probably a deep sea vessel.

“Right. So here I am. On a ship. A fishing ship. Buck naked in the dark. Way to go, Libby.” The sound of her voice calmed her slightly, even though the sound was swallowed up by the huge dark room she was in.
