“Not thatone,” Pega said. “The one your father sang on the way to Bebba’s Town.” She immediately began Brother Caedmon’s hymn, given to him by an angel in a dream.

Jack had to admit it was an excellent choice. For one thing, its soaring power put those whispering trees in their place. Jack couldn’t hear them, but he didn’t doubt that Pega could. For another, her voice was so marvelously fine. He’d been jealous of her at the Bard’s house, but he knew even then he was being unfair. She wasn’t a strong singer, yet her music filled the night. In the darkness you could believe you were listening to an elf lady.

Afterward they curled up together as they had in the hollow tree. No looming menace disturbed their sleep, and when they awoke, they found themselves covered with a blanket of the finest wool.

The little hollow was filled with a dim, green light. Jack could see sunbeams in the distance, but here the branches formed a dense mat. The air was heavy with the scent of lime flowers, and above, unseen, hummed a multitude of bees. For a moment Jack thought they had found their way into the Valley of Yggdrassil. But the hum wasn’t frenzied as it had been there. It was merely the sound of bees going about their usual chores.

“Where did this blanket come from?” whispered Pega.

“Elves?” guessed Jack.

“Brother Aiden said elves were completely selfish. Someone else left this, but what kind of people creep up on you in the middle of the night?”

“Maybe Brutus found a village and borrowed some things,” Jack said doubtfully. “I could shout for him, but—”

“It doesn’t seem quite safe,” Pega finished.

“He’s gotto be here somewhere. He probably went to the stream to fill the empty cider bags,” said Jack. “He would have returned for us, unless…” Unless he never got out in the first place,the boy thought. But, no, they would have heard Brutus shouting if anything had gone wrong. It wasn’t like the slave to go quietly into a knucker hole.

The trees weren’t as threatening as they had seemed the night before, but they still made Jack uneasy. “This is an odd kind of wool,” he said, feeling the fine, soft weave. From underneath, it was visible, but when he spread it on the ground, it vanished.

“It’s magic,” Pega said. “I’ve heard about cloaks of invisibility in stories. We’ll have to be careful, or we’ll lose it.” She folded it up and put a rock on top to mark its position. “Look!” she cried. She pounced on what Jack had thought was a large mushroom bulging out of the tree roots. The top of it came off, and a delicious smell wafted through the hollow. “It’s a pot and it’s full of bread and the bread’s still warm!”

Jack was by her side in a flash. “There’s more,” he said in wonder. Other mushroom-shaped containers revealed butter, honey, and golden rounds of cheese. The invisible creatures had even thought to provide wooden butter spreaders.

“Oh, thank you, thank you, whoever you are,” called Pega. “I swear I’ll do something nice for you, just name—”

“Hush,” said Jack, covering her mouth. He knew from stories that it was dangerous to make promises to things you couldn’t see. “We’re both extremely grateful,” he said, formally bowing to the trees around. “We’d be really happy to share this meal with you.”

But the forest was silent except for a faint breeze working its way through the branches and the bees humming all around. In the distance an unknown bird warbled and trilled.

Pega tore the bread apart and slathered it with butter and honey. She passed a chunk to Jack. “Do you think this food is enchanted?” he said, pausing with his hand in midair.

“I don’t care!” Pega bit into her chunk and added, in a muffled voice, “You can wait to see if I turn into a grasshopper. At least I’ll be a well-fed grasshopper.”

Jack couldn’t resist the smell of melting butter. He began devouring the warm bread, and it was even better than it smelled. The honey was as fragrant as a field of clover, and the cheese was sharp and wonderfully satisfying. He stuffed two rounds of it into his pockets for later.

When they were finished, they sat back in a kind of happy daze, too contented to move or talk. “We ought to wash our hands and faces,” Pega said after a while.

“Hmm,” said Jack. They sat a while longer, until the sound of a little, bubbling stream roused them. “I could use a drink,” Jack murmured.

“Me too,” said Pega. Time passed.

“We should move,” Jack said. He forced himself to rise. The green stillness of the hollow lay heavily on his body and urged him to lie down again. It’s a fine old bed, earth is,whispered a voice in Jack’s mind. You can pull the moss over you and sleep for a hundred years.“Get up,” cried Jack, suddenly alarmed. He dragged Pega to her feet and forced her to walk around. Once they were out of the hollow, Jack stamped his feet to get feeling back into them. Pega slapped her arms.

“What was that?” she said, her eyes wide and frightened.

“I don’t know. The trees, maybe. I never trusted them.”

They walked to the stream and washed their faces and hands. The cold water revived them.

“We mustn’t get too comfortable,” Jack said. “When I was in the Valley of Yggdrassil, I lost all track of time.” He stopped and remembered the drowsy enchantment of that place. He’d still be there if it hadn’t been for Thorgil. “We’ve got to remember our mission. Everyone’s depending on us. We have to find the Lady of the Lake and bring the water back to Bebba’s Town. King Yffi won’t wait forever.”

“That’s funny. I completely forgot about Yffi.” Pega waved her hand in front of her face as though brushing away spiderwebs.

“Magic does that. We have to keep reminding ourselves why we’re here. We have to keep saying people’s names. If I forget, you remind me.”

Pega fetched her string bag and removed the candle Mother had given her. “Smell,” she commanded.

Jack did so, and his head cleared at once. He remembered the village with its fields and houses. He saw the blacksmith fashioning a farm tool on his anvil, the baker pulling bread from his oven, and Mother sitting at her loom.

“You see,” Pega said, sniffing the fragrant wax herself, “the need-fire came through this. It will light our way back home.”

“You’ve learned more than I realized,” said Jack gravely.

“I listened a lot. Slaves do,” she replied.

They went back to the hollow to retrieve the blanket, but it was gone and so were the pots. “I suppose the owners took them,” said Pega. “It’s only natural. Now what do we do?”

Jack hung his head, trying to come up with a plan. “I wish I knew where we were,” he said. “Maybe the Lady of the Lake is here, and maybe she isn’t. Brutus could have found her, or he might have stumbled onto a dragon. We definitely can’t go back down that tunnel.”

In the end they kept on walking, keeping the trees to their left and the mountain to their right. They passed ghostly birches, aspens with leaves that twinkled in the wind, giant oaks with moss trailing like hair, and monstrous yews. The meadow through which they traveled was alive with small animals. Once, they saw a lynx watching them with round yellow eyes, and another time they crossed a stream where green butterflies drifted to and fro over banks of valerian.

It was a surpassingly beautiful place, yet ultimately, it was disappointing. They found no trails and saw no houses or the smoke that would come from houses. “Where are the people?” Pega said. In late afternoon they came to a rift in the trees where a tongue of rock jutted out of the mountain. They walked along the top.
