Eaters of the dead connection

I'm reading this book called "Eaters of the dead" and I found a connection . In the text it says, "That night we beached upon a rocky shore made of stones the size of a man's fist, and there Buliwyf, the land called Yatlam". I connected to this because when I went to the beach with my family I ended up seeing this small rock about the size of a man's fist along the shore. It wasn't too small or too big it was medium size. We also found another one but it was a little bit more big, about two fists. Did you ever find a rock that's about the size of a fist?
