Suddenly teeth sank into Lionpaw’s shoulder and claws dug into his flank.

Heatherpaw was dragging him off. “Stop it!” she shrieked. “What are you doing?”

Startled by the terror in her voice, Lionpaw froze. Crowfeather lay among the green ferns by his forepaws, bright red blood bubbling at his throat.

Heatherpaw crouched over her mentor. “Crowfeather!”

“I’m okay.” He lifted his head. Heatherpaw backed away as he staggered, spluttering, to his paws.

Shame seared Lionpaw’s pelt. The warrior code told him he didn’t need to kill a cat to prove the battle was won. If Heatherpaw hadn’t stopped him, he would have left Crowfeather dead.

What have I become?

Suddenly the light changed.

The bright morning air softened into shadow. Dawn seemed to give way to dusk. The birds fell silent. The screeching and wailing of battle ceased. Even the buzz of insects quieted as darkness seeped through the trees.

Lionpaw looked up.

The sun was disappearing, swallowed by a great black disk, darker and more sharply defined than any cloud.

“What’s happening?” Heatherpaw’s terrified mew hissed in Lionpaw’s ear, but he couldn’t answer. His voice was trapped in his throat, and his claws rooted him to the ground. Around him the air chilled. And above, the sun vanished completely, plunging the forest into night.

“StarClan’s killed the sun!” The shriek of a WindClan warrior rang through the forest. Instantly cats began wailing, and the woods shivered as they fled, their paws thrumming through the pitch-black forest.

“We’ve got to get home.” Crowfeather coughed. He dragged at Heatherpaw’s scruff as she stood petrified beside Lionpaw. “Come on!”

Wild-eyed, Heatherpaw turned to follow her mentor.

“I won’t forget,” Lionpaw hissed in her ear.

As she disappeared into the forest, he watched the sun’s dying rays bleed from the edge of the wide black circle.

CHAPTER 16

Jaypaw pressed his nose to Sorreltail’s paw. Leafpool had swathed it in damp comfrey leaves, and it seemed cooler already. “How does it feel?”

Sorreltail lifted it. “Much better.” She glanced toward the barrier. “I should get back to the fighting.”

“No.” Leafpool was cleaning up Mousewhisker’s eye beside them, soaking away the blood with wet moss. “ShadowClan are helping us now and, by the sound of it, there are going to be enough injuries to treat without you getting another.”

“But the fighting’s getting closer,” Sorreltail argued.

Leafpool shook water from the moss. “In that case we might need you here.”

Although the camp felt empty, the forest rang with the chilling sounds of battle. Jaypaw pricked his ears to listen more closely. Firestar’s patrol was fighting WindClan just above the hollow. Had they really been driven back that far?

“Shouldn’t we take the injured cats into the den?” he prompted. Spiderleg was already resting there, calmed by poppy seeds, his bleeding stanched by cobwebs. “It’ll be safer.”

If the camp is overrun.
