A half-moon glowed on smooth granite boulders, turning them silver. The silence was broken only by the ripple of water from the swift black river and the whisper of trees in the forest beyond.

There was a stirring in the shadows, and from all around lithe dark shapes crept stealthily over the rocks. Unsheathed daggers glinted in the moonlight. Wary eyes flashed like amber. And then, as if on a silent signal, the creatures leaped at each other, and suddenly the rocks were alive with wrestling, screaming warriors.

At the center of the frenzy of fur and claws, a massive dark brown haired man pinned a red haired man to the ground and drew up his head triumphantly. "Oakheart!" the first man growled. "How dare you hunt in our territory? The Sunningrocks belong to ThunderClan!"

"After tonight, Tigerclaw, this will be just another RiverClan hunting ground!" the red haired man spat back.

A warning yell came from the shore, shrill and anxious. "Look out! More RiverClan warriors are coming!"

Tigerclaw turned to see sleek wet bodies sliding out of the water below the rocks. The drenched RiverClan warriors bounded silently up the shore and hurled themselves into battle without even stopping to shake the water from their clokes.

The dark haired man glared down at Oakheart. "You may swim like otters, but you and your warriors do not belong in this forest!" He drew back his lips and showed his teeth as the man struggled beneath him.

The desperate scream of a ThunderClan she-warrior rose above the clamor. A wiry RiverClan man had pinned the brown haired warrior flat on her belly. Now he lunged toward her neck with his body still dripping from his swim across the river.

Tigerclaw heard the cry and let go of Oakheart. With a mighty leap, he knocked the enemy warrior away from the woman. "Quick, Mousefur, run!" he ordered, before turning on the RiverClan warrior who had threatened her. Mousefur scrambled to her feet, wincing from a deep gash on her shoulder, and raced away.

Behind her, Tigerclaw spat with rage as the RiverClan warrior sliced open his nose. Blood blinded him for an instant, but he lunged forward regardless and sank his dagger into the leg of his enemy. The RiverClan man shouted and struggled free.

"Tigerclaw!" The yell came from a warrior with a hair as red as fox fur. "This is useless! There are too many RiverClan warriors!"

"No, Redtail. ThunderClan will never be beaten!" Tigerclaw yelled back, leaping to Redtail's side. "This is our territory!" Blood was welling around his broad black face, and he shook his head impatiently, scattering scarlet drops onto the rocks.

"ThunderClan will honor your courage, Tigerclaw, but we cannot afford to lose any more of our warriors," Redtail urged. "Bluestar would never expect her warriors to fight against these impossible odds. We will have another chance to avenge this defeat." He met Tigerclaw's amber-eyed gaze steadily, then reared away and sprang onto a boulder at the edge of the trees.

"Retreat, ThunderClan! Retreat!" he yelled. At once his warriors squirmed and struggled away from their opponents. Spitting and snarling, they backed toward Redtail. For a heartbeat, the RiverClan cats looked confused. Was this battle so easily won? Then Oakheart yelled a jubilant cry. As soon as they heard him, the RiverClan warriors raised their voices and joined their deputy in caterwauling their victory.

Redtail looked down at his warriors. With a flick of his hand, he gave the signal and the ThunderClan warriors dived down the far side of the Sunningrocks, then disappeared into the trees.

Tigerclaw followed last. He hesitated at the edge of the forest and glanced back at the bloodstained battlefield. His face was grim, his eyes furious slits. Then he leaped after his Clan into the silent forest.

In a deserted clearing, an old gray haired woman sat alone, staring up at the clear night sky. All around her in the shadows she could hear the breathing and stirrings of sleeping people.

A small brown haired woman emerged from a dark corner, her footsteps quick and soundless.

The gray haired woman dipped her head in greeting. "How is Mousefur?" she asked.

"Her wounds are deep, Bluestar," answered the other woman, settling herself on the night-cool grass. "But she is young and strong; she will heal quickly."

"And the others?"

"They will all recover, too."

Bluestar sighed. "We are lucky not to have lost any of our warriors this time. You are a gifted healer, Spottedleaf." She tilted her head again and studied the stars. "I am deeply troubled by tonight's defeat. ThunderClan has not been beaten in its own territory since I became leader," she murmured. "These are difficult times for our Clan. The season of newleaf is late, and there have been fewer babes. ThunderClan needs more warriors if it is to survive."

"But the year is only just beginning," Spottedleaf pointed out calmly. "There will be more kids when greenleaf comes."

The older woman twitched her broad shoulders. "Perhaps. But training our young to become warriors takes time. If ThunderClan is to defend its territory, it must have new warriors as soon as possible."

"Are you asking StarClan for answers?" meowed Spottedleaf gently, following Bluestar's gaze and staring up at the swath of stars glittering in the dark sky.

"It is at times like this we need the words of ancient warriors to help us. Has StarClan spoken to you?" Bluestar asked.

"Not for some moons, Bluestar."

Suddenly a shooting star blazed over the treetops. Spottedleaf's eyes twitched and the hair along her arms bristled.

Bluestar's head lifted but she remained silent as Spottedleaf continued to gaze upward.

After a few moments, Spottedleaf lowered her head and turned to Bluestar. "It was a message from StarClan," she murmured. A distant look came into her eyes. "Fire alone can save our Clan."

"Fire?" Bluestar echoed. "But fire is feared by all the Clans! How can it save us?"

Spottedleaf shook her head. "I do not know," she admitted. "But this is the message StarClan has chosen to share with me."

The ThunderClan leader fixed her clear blue eyes on the healer. "You have never been wrong before, Spottedleaf," she meowed. "If StarClan has spoken, then it must be so. Fire will save our Clan."
