Red nail polish flashing, Gail wrung her hands. “Cassandra, you don’t have to go. You fulfilled my promise. He has no hold over you.”

She shook her head. She wasn’t going back because of promises or because of Gram’s story or to save her mother. “I want to return to him,” she said.

Owen wordlessly handed Cassie a stack of printed data. She thanked him and packed it. Scanning her desk, she found an ice screw. She added it to a side pocket.

“Cassie.” Dad dropped his voice low. “He’s not even human. You told me yourself you don’t know what he looks like when he isn’t a bear. You don’t know what he is.”

She was not going to fight with him.

Without a word, she marched through the lab to the bathroom. She slammed the door behind her and shoveled her toothbrush, deodorant, and shampoo into the bag. “I know perfectly well what he is,” she said through the door. “He’s Bear, and he’s my husband.” She rooted through the cabinets until she found one more item: birth control pills, left by an intern who’d worked at the station prior to Jeremy. She packed the pills and zipped the bag.

Flinging open the door, she added in a low voice, “And isn’t all this a little hypocritical coming from the man who married the North Wind’s daughter?” His jaw fell open, and she brushed past him. “Owen,” she called, “do you have the rest of those maps?”

“Just a minute here, young lady…” Dad strode after her.

Max emerged from his bedroom. “What’s going on? Cassie-lassie?” He followed Cassie and Dad back to where Gail waited. “What’s she doing?” Max asked.

“Ruining her future,” Dad said.

“Following my future,” Cassie corrected. Owen handed her another stack of maps, and then, with a quick glance at Cassie’s father, retreated across the room.

“You have a future here,” Dad said. “You have family and friends here. You’re giving up everything to be with this ‘husband.’ You’re giving up college. You’re giving up your goals. What about your plans to be a professional tracker? You always said that’s what you wanted.”

Cassie put on her hat and zipped her parka. Sweat heated in her armpits. “I shouldn’t have expected you to understand. After all, you left your wife in a troll castle.”

“Dammit, Cassie, I did that for you! You’d been born. I had to keep you safe! I couldn’t go traipsing off to the ends of the earth. I had to be a father to you!” He thumped a desk with his fist for emphasis. Papers scattered, and Owen jumped. “Do you think it was an easy choice?”

It hadn’t been a choice; it had been cowardice. Why else had he lied to her all these years, leaving it to Gram to finally tell her? Shame was a powerful motivator. She knew he wished he had rescued Gail. She’d heard the regret in his voice that first night when she’d eavesdropped on her parents. She slung her pack over her shoulder.

“I forbid it.” Dad blocked the exit. “You don’t know what you’re doing.”

Cassie turned to her mother. “You talk to him.”

“But I don’t…,” Gail began.

“History is repeating itself,” Cassie said. “Your father didn’t want you to leave either.”

Startled, Gail looked at her husband.

“It’s not the same thing at all,” Dad protested. But Cassie could see her mother understood. It was the same. Cassie watched her mother’s face as her father blustered. Every night, her mother woke screaming, afraid she would be imprisoned again. Would she let her daughter be kept somewhere against her will? Cassie didn’t know her well enough to be certain, but she was betting not.

Gail touched his arm with her red fingernails. “Laszlo, let her go.”

Aghast, he turned to her. “Do you know what you’re saying? You want to send our only child, our baby girl, back to the mercy of a bear?”

Gail lifted her chin and did not back down. Max, wide-eyed, looked back and forth among the three of them like he was watching a convoluted Ping-Pong game. Owen ducked behind the doorway of his workshop. Dad broke first. Lowering his eyes, he said, “Cassie, please, don’t do this. It isn’t safe. It isn’t smart. You’re rushing in again. Wait for a while and then decide. Don’t leave so soon.”

Gail reached toward Cassie and then let her hand fall. “Cassandra… Cassie… I was just getting to know you.” Cassie looked at her mother. What could she say? That no matter how much time she spent here, it wouldn’t be enough to bridge the lost years? Cassie couldn’t say that. Better just to leave.

“Stay with us,” Dad said. “We’re your family. This is your home. Please, think about this. Think of what you’re giving up.” Max’s eyes were overbright, and Gail had tears in hers.

Looking at them, Cassie started to blink fast. Her eyes felt hot. “Tell Gram I’m sorry I didn’t get to see her.”

She went outside quickly—before she could change her mind, or have it changed for her. Silence slammed down on her as she closed the outer door. She inhaled deeply, and cold bit her throat. Feeling her way along the perimeter of the station, Cassie raised the U.S. flag in the blinding white darkness of an Arctic blizzard.

CHAPTER 12

Longitude 153° 37’ 58” W

Altitude 6 ft.

As Bear carried her north, Cassie laid her cheek against the soft fur of his neck. She breathed in his scent—sea salt and damp fur. Above, the northern lights played between the stars as Bear ran across the endless ice. She thought of the last time Bear had carried her away from the station. Same ride, but now she knew what waited at the end of it.

Or at least she hoped she did. What if Bear rejected her plan?

After many hours, they reached the castle. Cassie saw the spires, luminous in the light of the moon. Bear slowed to a walk, his paws crunching on granules of ice.

“We’re home,” Cassie said softly.

Bear paused, and she knew he’d heard her. She wrapped her arms around his broad neck, and then she dismounted and walked through the shimmering castle gate with her hand resting on her Bear’s back.

She led him to the banquet hall and removed her pack. She unzipped it and began to pull out maps, binders, and notebooks and pile them on the banquet table. Frost curled around a map as she unrolled it. “Can you tell the table not to eat this?”

Bear focused on the table, and the frost retreated. “What is all this?” he asked.

Cassie took a deep breath. Time to see if she truly had a future here. For all her fine words to Dad, Bear could squash everything without even knowing he was doing it. If he was unwilling… I’ll have to convince him, she thought. She pointed to a section of the map. “Here’s the coast. And here are this season’s dens. One bear per triangle.” Cassie flipped open a three-ring binder. “This is a record of the denning dates with the predicted dates of birth, which I can use to plot routes for you that will bring you closest to the most likely births at any given time for the rest of the birth season. Predictive modeling. We can use it to change the odds.”

Bear furrowed his broad forehead.

She plunged on. “Eventually, with enough data points, I should be able to be precise… within an order of magnitude, of course.” Thanks to Owen, she had printouts of all the files from all the cooperating research stations. It wasn’t a complete record of the full bear population by any means, but it was a start. “Look,” she said, “I’ve already plotted a preliminary course. We can test it out tomorrow.”

She watched him, waiting for his reaction and trying to read his glass black eyes.

“You wish to come with me out onto the ice? Out to the births?”

“I have to,” she said firmly. “For this to work, we need to record more data, and you can’t do both jobs. Besides, you won’t know what data we need.” She tried a grin. “And you won’t have opposable thumbs.”

His laugh was a familiar and welcome soft rumble that washed over her, and then he was serious again. “All munaqsri travel alone. We must avoid detection—”
