braced himself against the cold. He kept a lookout for the white wolves, but he didnât see any sign of them as the sleigh sped across the moonlit plain.
Soon he could see a row of snow-covered hills in the distance. âLook!â he said. âThere it is!â He pointed to one of the hillsâthe only one without a peak.
âTie her down!â Annie shouted.
Jack tied a knot in the string, and the sleigh began to slow down. He tied a second, then a third. The wind died down completely, and the sleigh coasted to a stop at the foot of the Hollow Hill. Jack and Annie climbed out.
Jack looked up at the steep white slope. âHow do we get inside?â he said.
âI donât know,â said Annie. âHow do you think the Frost Giant gets inside?â
âOh â¦Â the Frost Giant,â said Jack. He really wished Teddy and Kathleen were with them. He felt as if part of their team was missing.
Annie seemed to read his thoughts. âWe can do it,â she said. âWe have toâfor Morgan and Merlin.â
Jack nodded. âYouâre right,â he said. They studied the hill in the moonlight.
âUp thereâis that an opening?â said Annie.
âMaybe,â said Jack. âLetâs climb up and check it out.â When they climbed a little way up the hill, Jack could clearly see a break in the snow-covered slope.
âLetâs see if it leads inside!â said Annie.
âWait, what about the Frost Giant?â said Jack.
âI have a feeling heâs not here right now,â said Annie. âWeâd better go in and find the wizardâs eye before he comes back.â
âOkay,â said Jack. âBut be careful!â
They scurried farther up the slope. When they came to the opening, they stepped through the huge crack into the hill.
Jack and Annie found themselves on a ledge above a deep, rounded hollow. Moonlight flooded down through the open hilltop. At the bottom of the hollow was a flat spot where it looked as if the snow had been blown in circles.
âThat must be where the giant sleeps!â said Annie.
âYeah, and itâs probably where he hides the eye,â said Jack. âWe just have to find a hole. Remember?â He repeated what the Norns had said:
In the Hollow Hill is a hole.
In the hole is a hailstone.
In the heart of the hailstone
Hides the wizardâs eye.
âRight,â said Annie.
Jack looked down at the snowy swirl. He looked back at Annie. âOnward?â
âOnward,â she whispered.
Jack and Annie scrambled down into the hollow. Stepping carefully through the silver moonlight, they studied the ground, looking for the hole.
Annie stumbled and fell. âWhoa!â she said. âI think I just found the hole! I stepped in it!â
âReally?â said Jack. He knelt down beside her.
Annie reached down into a small hole in the floor of the hollow. âThereâs something in here!âshe said. She pulled out a chunk of ice the size of an egg. âThe hailstone!â
In the dim light, it was impossible to see if anything was inside the ice chunk. âWe donât know if this is the right hailstone,â said Jack. âWeâll have to wait till daylight to see if the eyeâs in there.â
âIt has to be the right one,â said Annie. âHow many hailstones are hidden in a hole in a hollow hill?â
âGood point,â said Jack.
Annie turned the hailstone over in her hand. âMaybe the eye is looking at us now,â she said.
âThatâs scientifically impossible,â said Jack. âAn eye canât see unless itâs connected to a brain.â
âYeah, and a string canât make the wind blow, either,â said Annie. âForget science in this place. Waitââ She caught her breath. âDid you feel that?â
âFeel what?â said Jack.
âThe groundâs
