He opened his eyes to the sound of waves. Warm sand clung to his skin. As he sat up, all he could see was an empty beach stretching endlessly in both directions.

He tried to say his own name, but not a single word came to mind. He couldn't remember who he was or how he had ended up there. Just as he got to his feet, he noticed something faint written on the inside of his left forearm.
