Bone breaks Shawn's hand

He tried a left. The better punch, since I couldn’t deflect it without releasing his hip. I turned my head and took his knuckles on my frontal bone, the hardest section of my battle-hardened skeleton. I heard something snap. Most likely a metacarpus. Shawn yanked his hand back, crying out in pain.

“Aimed too high,” I said. “Kidney shot was the go.”

“You broke my hand motherfucker!” he said.
