“Thunder, stop!” George shouted, his voice hoarse. But Thunder kept running, the creature leading him farther into the night. George’s boots skidded on a rock, sending him crashing to the ground. Pain shot through his knee, but he ignored it, scrambling back to his feet. He couldn’t stop. Not now.
The sound of Thunder’s hooves grew fainter, and George felt a surge of desperation. He forced his legs to move faster, the adrenaline dulling the pain in his knee. Every step was agony, but the thought of losing Thunder again was worse.
