Steeling his nerve—for Jack knew all the Northmen were quick to anger—he said, “How did you get that?”

“EH?” said Eric, whose ears had been dulled by years of blows and who bellowed all the time.

“How did you get that?” Jack pointed at the scar.

A ragged smile broke out on Eric’s face. “TROLL BITE,” he replied.

“It’s—it’s so big.” Jack’s stomach did a flip-flop as he calculated the size of the mouth that had caused the damage.

“NAW, IT WAS A LITTLE BUGGER. GOT HIS TOOTH HERE.” Eric hauled up a lump hanging on a thong around his neck. It was a fang the size of a billy goat’s horn. Eric, not much on conversation, went back to bailing.

These people are crazy,thought Jack as he bent to work. I couldn’t drive them mad even if I knew how. They’re already as loony as the crowd in the Valley of Lunatics. They deserve to spend eternity in Valhalla.

At last the three ships reached a lonely island, where a small colony existed. Low houses made of turf bulged out of the soil. They looked like small hills. Or graves,Jack thought with a shiver.

This was the last stop before the ships turned east. They would sail out of sight of land now. They would be alone on the gray ocean with only the whales—or troll-horses, as Olaf called them—for company.

The warriors traded for freshwater and dried fish. One last time Jack looked at the land as it fell behind them. It was barren and windswept, but to the far west lay a gentle light. It was as though something lay shining beyond the margin of the sea. It was the Islands of the Blessed, where the old gods ruled and where the ancient heroes and heroines still had their dwelling. Perhaps the Bard was there, sitting under an apple tree.

To the east, the direction they were traveling, the sky was leaden. No light there. Jack sighed and felt for the rune of protection. So far it had done its work. He and Lucy hadn’t been murdered. They weren’t shut up in one of those dark Pictish towers. Of course, he was miserable and Lucy wasn’t far from madness, but the rune promised only life, not happiness.

The unending water filled Jack with a kind of dread. With each day his home fell farther behind on the trackless waste. Even if, by some magic, he was able to gain control of the ship, he could not ply the oars or reef the sail. He would never find his way back.

Jack felt helpless, like a bug on a floating leaf. Anything could send the leaf spiraling down. Or a sea serpent could rise and swallow the ship. Olaf swore he had seen one on the way over.

Lucy stared at the gray expanse with listless eyes. “I want trees,” she said. “I want it to stop moving.”

“Me too,” said Jack. The seasickness he’d had in the early days came back. The ship slid up and down in a gut-wrenching way. When it didn’t meet the waves directly, it tipped to one side, sloshing the bilgewater over everyone’s feet. Jack understood now why the Northmen’s boots smelled so vile.

At first the wind was gentle but steady enough to fill the sail. The warriors lounged around and played a board game called Wolves and Sheep with movable pegs that fit into seven rows of holes. A peg in the middle was the wolf. Around it was ranged a flock of thirteen sheep. The object was for the sheep to crowd the wolf into a trap, while the wolf tried to devour the sheep. It was an interesting game, and Jack watched it when he wasn’t being sick.

But soon the wind strengthened. Foam began to form on the tops of the waves. Oh no! Not another storm,Jack thought. The mast creaked ominously, and Olaf gave an order to shorten the sail. The warriors bent to their oars. “Now would be a good time to use your skills,” rumbled the giant from over Jack’s head.

Jack knew what Olaf wanted. He was supposed to calm the waves, and he didn’t know how. He wasn’t really a bard, in spite of what he had allowed Olaf to believe.

The terrifying Northman loomed over the deck. Everything, from his smelly boots and tree-trunk legs to his ice blue eyes peering out from under a single, bushy brow, spelled doom. Jack knew he had to do something quickly.

“I need complete silence,” he said, inwardly quaking with fear.

“You louts keep quiet!” roared Olaf at his crew. “If I hear one word, I’ll send whoever it is to Aegir’s halls. Anything else?” he asked Jack.

“I want Lucy at the other end of the ship. Feed her sweets or something to keep her quiet. She’s too little to understand. But if I hear Thorgil hurting her, I’ll stop doing magic.”

“Fair enough,” said Olaf, lumbering to the stern to threaten Thorgil.

The wind was stronger now. Waves were beginning to spray over the side. Two of the warriors stopped rowing and started bailing.

The only thing I know is how to make fog,Jack thought desperately. What good is that? And how can I do it here, out of sight of the trees and land?Then, as though a voice were speaking in his ear, he remembered something the Bard had said: I was telling you about how the life force flows in streams deep in the earth. It is this that feeds the great forests and meadows sweet with grass. It is this that calls forth the flowers and the butterflies that are so like flowers. The deer follow its courses as they browse. The badgers and moles build their homes over it. It even draws the swallows in the midst of the sea.

In the midst of the sea! If birds could feel the life force in the air, he could certainly call to it down here. Jack closed his eyes and felt with his mind the bowl of ocean surrounding him. He breathed in the sharp odor of the wind. He heard—yes, heard!—the moans of the whales as they followed their paths over the deeps. He cast his mind down to where the light failed and found, far below, a current of fire. Come forth,he called. Come forth to me. Cloak the air with your gray presences. Bring sea and sky together.

Sunlight muted. The wind faded—was it leaving him or he it? Dampness flowed into his lungs. Water soaked into his clothes, but it was a clean wetness, not like the bilgewater. After a while he opened his eyes and saw Olaf looking—was it possible?— scared.

A heavy fog cloaked the sea, and the ship bobbed gently. Of course. Fog and wind did not happen together. Without realizing it, Jack had hit on the one thing that would calm the waves. I did it,he thought exultantly. I’m a real bard.

But he remembered what had happened when he stopped calling up fog by the Roman road. The wind had risen, blowing the clouds away and revealing him and Lucy to the Northmen.

Jack closed his eyes again. He reached out to the life force and found it everywhere. It swirled in the hidden currents far below, carrying a flurry of creatures that glowed in the dark. Jack had never seen such things before. He didn’t know how he could see them now. He felt the quicksilver movement of a school of fish near the surface. He felt a crow coasting the upper air above the fog bank. Sunlight polished its black feathers.

A crow? What was a land bird doing so far from shore? As far as he knew, crows couldn’t swim. They weren’t like seagulls. He remembered finding one drowned in a farm dam. Its fellows filled the trees, cawing and clacking their beaks as though they were at a funeral. Their behavior had impressed him so much, Jack had waded into the water and taken the poor creature out. He laid it on a rock for the sun to dry—it seemed somehow better for it to rest under the sky. And all the while the other crows sat in the trees, cawing and bowing as they shifted their feet on the branches.

This bird, the one above the fog, must have been blown away by the storm. Jack felt its extreme tiredness. Its wings ached. Its chest labored to breathe. It wouldn’t be able to go much farther. Come down,Jack thought. Come to me.He didn’t know why he was doing this or whether the bird could even hear him. He couldn’t protect himself or Lucy, let alone an exhausted crow. But it seemed terrible to let the creature fall into the sea.
