“Are we close?” Cassie asked.

“I will bring you to the end of my region,” the lemming said, “and the owl will arrange for a guide to bring you into the forest. You will be with Father Forest by tomorrow afternoon.”

Cassie felt her heart leap. She could see Bear tomorrow! Finally, after the ice and the sea and the tundra… Cassie ran her fingers through her hair, and her fingers snagged a few inches from her scalp. She hoped he didn’t mind that she smelled. Cassie laughed out loud and shook her head. Her hair flew around her in a red cloud of tangles. “I’m coming, Bear!” she said. She’d bring him home. She touched her stomach. And then? She didn’t know.

CHAPTER 22

Latitude 64° 04’ 50” N

Longitude 124° 56’ 02” W

Altitude 1281 ft.

She’d be met by a guide, the lemming had said before he’d left her, but Cassie didn’t see anything that looked like a guide. She was alone at the foot of a hill. Spruces studded the low rise, and an aspen grove blocked her view over the top. The air crackled with birds and tasted faintly of evergreen. “Hello?” she called. She wondered what kind of creature she was supposed to meet. Rodent? Bird? Mosquito?

One of the aspen trees halfway up the hill began to shiver. Aspens, northern aspens, quiver in a breath of wind. She remembered one of Dad’s lessons: Populus tremuloides, they were called. Quivering aspens. But this was the only tree in the grove that was moving. She walked up to it. Its trunk was as thick as her arm, with bark a peeling pale green. Thin branches jutted out at uneven intervals.

It jiggled harder, as if it were doing a belly dance.

And then suddenly it laughed. Or, more accurately, a girl perched in the branches laughed. Cassie squinted—the sun was directly behind the tree and, oddly, made the girl appear greenish.

“Hellooo!” The girl waved. She swung out of the branches and landed lightly on the ground. “I am the aspen.”

Cassie blinked at her. She was green. Her skin looked like layered leaves, and her hair looked like twigs. “You’re the aspen munaqsri?”

“Yes,” the girl said. Her voice was high, whistlelike, and cheerful.

“You’re a tree,” Cassie said.

Again, the green girl laughed. “Yes!”

Cassie decided that she’d seen stranger things than this. Or maybe she hadn’t. She tried to imagine describing this creature to Owen and Max. They’d never believe her. Gail might. If Cassie went back to the station now, maybe she and her mother would have something to talk about.

Following the aspen, Cassie climbed to the top of the hill, and the view banished all other thoughts. All Cassie could do was stare. “Wow,” she whispered. It was gorgeous. Far in the distance, she could see mountains, the Mackenzies. Dark purple with streaks of glacial white, the mountains crowned the horizon. Max had always wanted to fly his Twin Otter in the Mackenzies. Now she could understand why. Rivers cut through the foothills. She saw enormous rock faces. And the green… oh, the green. Spruces, thick and tall, dominated the landscape for the hundreds of miles between her and those foothills. Pale green tamarack and the slender spines of aspens stood out like lights against the rich spruce green.

“Father Forest is within the boreal forest,” the tree-girl said. “We will ride there.”

“Ride what?” Cassie asked.

Seeming to ignore her, the aspen pointed. “I like that one,” she said. She was pointing at a nearby caribou, a young buck. His back was to them. He had shed most of his winter coat, but remnants hung like rags on his broad neck and back. He lowered his head into a thicket and thrashed his antlers against the branches. It sounded like a dozen snare drums; it drowned the chirps of birds. Finishing, he lifted his head. His antlers were tinted red. Cassie could hear larks and thrushes again. The tree-girl sprinted to his side, as fast as a blur.

Grinning, Cassie followed her. This was even better than traveling by lemming. The aspen-girl sprang onto his back and beckoned to Cassie. Grasping the caribou’s mane, Cassie pulled herself onto his back. The length of her pack forced her to lean toward his neck. His vertebrae stuck into her legs.

“Run!” the aspen commanded.

He broke into a gallop, and the other caribou scattered. His tendons clicked with the unique caribou sound, like rubber bands snapping. Cassie bounced on his bony back as he accelerated to munaqsri speed under the aspen’s power.

She knew the moment they left the taiga and entered the boreal forest: The light changed. Shadows surrounded them as conifers blocked the sun. The caribou ran over needles that crunched, and he leaped over fallen trees. Spruces were swathes of dark green punctuated by the white flash of an aspen. Finally, she was almost to Father Forest!

The aspen shouted a command, and the caribou stopped. Cassie was tossed into his neck. “Ow!” Her stomach squished. She scooted back behind his prominent shoulder blades. “Why did…,” she began to ask, and then she stopped.

Ahead was a picturesque cottage nestled in spruces. It looked as if it were part of the spruces. The bark of the trees bled into the wood of the walls. The roof was made of mossy stones. Cassie smiled—the cottage defined “quaint.” Wild roses curled appealingly around the door and windows. The air smelled of rosemary and mint. Smoke curled invitingly from the chimney. Ferns covered the tiny yard, and wide slate stones made a path to the door. Cassie slid off the back of the caribou, and the caribou trotted away.

Opening a wooden gate, Cassie stepped on the first stone. She heard a chime like a chorus of birds. Passing her, the tree-girl skipped, laughing, down the path. Each stone sang out under her feet. It sounded like a bird-call xylophone. Cassie tested another stone. It chimed for her. Grinning, she went down the path toward the cottage door. She could smell bread baking. She inhaled deeply.

The tree-girl flung the door open. Cassie stooped in the doorway. She squinted, her pupils expanding. Inside, the cottage was as dark, snug, and comfortable as a bear den. It took a second for her eyes to adjust before she saw the cottage’s occupant.

The old man was as bent and gnarled as a black spruce tree. Broom in hand, he scuttled around the tiny home sweeping dirt from the corners and the ceilings. Dust hung in the air like morning haze. He muttered to himself. The tree-girl threw her arms around him. He patted her absently on the shoulder. “Yes, yes, dear,” he said. “But everything must be perfect for our guest.”

Father Forest. She wanted to shout or sing. Bear seemed so close she could almost feel his fur under her fingers and smell his seal-tinged breath. Cassie cleared her throat.

He clapped his hands together. “Our guest!” All his wrinkles seemed to smile. “Please, come in, come.” He fussed around her as she ducked inside.

The cottage kitchen was full of cabinets and drawers, all carved with pictures of rabbits and squirrels. Shelves were stacked with wooden plates, bowls, and pitchers. The sink even had a wooden faucet. The only metal was a wroughtiron stove with an old-fashioned teakettle. Corners of the kitchen receded into shadows. She saw a small, cozy living room through an open doorway, and through one of three other doorways, she glimpsed a bedroom. It was nothing like Bear’s castle with the open ballroom, the buttressed halls, the spiral staircase, but she liked it. It felt warm and safe and a welcome change from ice and tundra. “You are Father Forest?”

The old man bobbed his head. “Do you like it?”

He must mean the forest, she guessed. “It’s beautiful.”

He beamed. “You must see the Aberdeen Lake area. Beautiful white spruces. And the Peacock Hills. Some of my finest work. Yes, you must have a tour! You should see my aspen groves. And the riverbanks with the balsam poplars. The rivers are not my region, of course, but, ah… the riverbanks!”
