Sam could see the creatures writhing within Pack Leader’s skin. Like he was a baggie full of worms.

“Ready?”

“I am Pack Leader,” the coyote said. He tilted back his head and howled at the sky.

Sam aimed both his palms at the beast just as his hide split open.

The killing light burned and burned. Pack Leader was dead instantly. His fur stank as it burned. His flesh crisped like bacon.

The creatures, the insects, whatever they were, crawled out of the flames and popping fat. Unfazed. Unharmed. Bright-lit and yet seemingly invulnerable.

Sam had used his power to burn through concrete and solid rock and steel. It was impossible that he couldn’t kill these things. It was like they had some magical power to shrug off his deadly light. Like they had developed an immunity to him.
