power glows

"Thomas," I said. "Glau's running."
"Relax," Thomas said, and his eyes never left Madrigal.
I heard the scrabble of claws on gravel and then Mouse shot out of the shadows that had hidden Thomas. He flashed by me in what was for him a relaxed lope, but as Glau approached the van, Mouse accelerated to a full sprint. In the last couple of steps before Glau reached the van, I thought I saw something forming around the great dog's forequarters, tiny flickers of pale colors, almost like Saint Elmo's fire. Then Mouse threw himself into a leap. I saw Glau's expression reflected in the van's windshield, his too-wide eyes goggling in total surprise. Then Mouse slammed his chest and shoulder into Glau's back like a living battering ram.
The force of the impact took Glau's balance completely, and sent the man into a vicious impact with the van's dented front bumper. Glau hit hard, hard enough that I heard bones breaking from fifty feet away, and his head whiplashed down onto the hood and rebounded with neck-breaking force. Glau bounced off the van's front bumper and hood, and landed in a limp, boneless pile on the ground.
Mouse landed, skidded on the gravel, and spun to face Glau. He watched the downed man for a few seconds, legs stiff. His back legs dug twice at the gravel, throwing up dust and rocks in challenge.
Glau never stirred.
Mouse sniffed and then let out a sneeze that might almost have been actual words: So there.
