Flustered, Ash set aside the subject. She glared at the trees. She was beginning to hate them. The ground was spongy here. It was strange to crunch through hard snow and then feel the earth spring back. Perhaps that was one way Lan navigated, the texture of the earth beneath his feet.

Deciding she'd had enough walking, Ash stilled the gelding and mounted. The sound of leather snapping and metal striking metal broke the silence like a series of small explosive charges. She had not realized how quiet the forest was until that moment. Birds weren't even calling.

"Stay where you are." Lan Fallstar's voice came from a white and hazy point in the distance.

She could not see him, even with the extra height of the horse. With an expert adjustment of the reins she turned the gelding in the direction she hoped was east. Away from Lan Fallstar. The sturdy little horse seemed up for a trot and struck a path through the mist. The crowns of the birches were so high that hitting branches wasn't a problem, and the birches themselves were spaced well enough apart that a way through could be navigated at a trot. It felt good to ride away. She had agreed to become Sull at an unknowable cost to herself and Raif Sevrance. She had not agreed to trot behind a Sull Far Rider like a.

She was Ash March, foundling, left outside Vaingate to die. That had not drained away with her blood. She was almost-daughter to a surlord, and that had not changed either.

Ark Veinsplitter and Mal Naysayer had treated her with respect. Daughter, Ark had called her. Lan Fallstar didn't even use her name. So why was she so anxious to please him?

It was all very confusing. Like the birch way. Glancing around, Ash realized she had no way of telling how far she and the gelding had come. Every tree looked like the one she had just passed. A stirring of wind had made the mist choppy, and clouds sprayed up in loose waves. Slowing the gelding to walk she breathed it in and tried to calm herself.

She could hear no sound of pursuit. Now that the heat was leaving her she felt foolish and a bit afraid. Would it be possible to retrace her steps? A look over her shoulder revealed a landscape of haunted trees. If Lan Fallstar stood amongst them he was hidden by the mist.

The stubborn part of her wanted to continue on her path, just carry on going and somehow muscle her way out, but the practical part warned her to go back now while she was still pretty certain how far she had come. This was Sull land, she reminded herself. She could not be entirely sure that the mystery of the birches was purely physical. Strange sorceries might be woven between the trunks. Ark had told her about the Sull maygi and necromancers, men and women who birthed ancient magics by the dark of moon and lived apart in high sea caves and open towers. It would be only natural that such powers be used in defending the one thing they cared about above all others: defending their borders. What if she could never escape?

"Come on, boy," she said, kicking her heels into the gelding's belly and making the creature turn. This wasn't going to be pretty, having to return to Lan Fallstar with her tail between her legs, but it would be a lot less pretty if she turned insane and started loving the trees.

It took her over an hour to find him. Lan Fallstar was leaning against a birch, peeling an apple with her sickle knife. The knife's weighted chain swung lazily between his legs as he cut a continuous strip from the fruit. He studied Ash as she approached but did not speak. Ash pressed her lips together and made herself busy dismounting the gelding, removing its bit, and loosening its belly cinch. "This Sull hopes you enjoyed your ride." Ash had been in the process of unfastening the saddle straps and she had her back toward the Far Rider. She paused, fingers on the brass buckles, and thought of several ways to reply. None of them friendly. He had known she would come back. This annoyed her. She was annoyed also by the fact that he was using the knife that had been given to her as a gift by Ark Veinsplitter.

As she turned to give him a piece of her mind, he held the peeled apple and the knife out toward her and said, "They are yours." His sharply beautiful face was hard to read. "Take them."

Ash came forward and stopped a few feet before him, suddenly awkward. He pushed himself off the tree and took the remaining steps to meet her. Holding out his palms he offered her the apple and the knife. The exposed meat of the apple was starting to brown. If there was a trap here she could not discern what it might be. Quickly she took the items from him. Their hands and wrists touched briefly, and the contact and the whole situation felt so confusing she had to turn away.

"You can give the apple to the horse. This Sull will not be offended."

Surprised by the humor in his voice, she looked over her shoulder. Lan Fallstar was smiling, and it was such a warm and unexpected sight that she smiled right back at him. She was aware of an immense sense of relief, but hardly knew why.

"When two people are parted in the birch way it is best if one stays close to the original point. That way it becomes possible for the second person to find her way back."

Ash nodded softly. After days of short and impatient replies, his explanation seemed like a kindness. Now it was she who had nothing to say to him, and she wrapped the chain carefully around the sickle blade's handle and went to feed the apple to the gelding.

Not long after that they headed on their way. The mist was finally breaking up and cold white sunlight slanted through the birches. Lan's pace was a fraction slower than before and she found herself drawing abreast of him more often. Briefly Ash wondered why they had to walk the birch way and could not ride. She thought about asking him, but stopped herself. She did not want to test this new goodwill between them.

With the mist gone the birches began to gleam like bones. Thousands became visible, layers and layers of trees stretching toward the horizon on all sides. Ash was glad to see her feet and found herself looking at them often. The variety of materials squelched by her boots was the only thing that changed in the landscape. The air smelled faintly of methane, and she wondered if part of the birch way was a bog. If they strayed too far off course here might they sink? For a while she tracked Lan's gaze as it slid through the trees, hoping to discover something about his methods of navigation, but she lost interest after a while. Her hands and wrists still felt hot where he had touched them. Lan said, "Let us stop here."

It was earlier than they would normally stop, but Ash was glad. She was hungry, and tired of looking at trees. As she unstrapped the fallen timber she had collected, the Far Rider set about unpacking his saddlebags. When she realized he was sliding out the tent, muscles in her stomach contracted in a way that made her feel half sick and half excited. Fumbling with the logs, she managed to drop a couple against the gelding's back hoof. "Sorry," she told the horse, kneeling awkwardly to pick them up.

After she'd built the fire and lit it she waited to feel more relaxed. The ground was dry here and she threw down her saddle and sat on it. Lan had finished pitching the tent and was now preparing their supper. She had come to him empty-handed—her saddlebags had been lost south of the Flow—and she was dependent upon his cooking utensils and food to eat. When she had met him she had been living on horse blood for seven days.

Lan cut up slices of cured horsemeat and dried mushrooms and put them in a pot with rich yellow kidney fat, cardamom seeds, and snowmelt. He worked quickly and with precision, using the same knife he had burned his skin with the night they first met. When he was done he cleaned the blade with oil that smelled of cloves, and a scrap of deerskin, and then sat in silence while the water in the pot came to a boil. A full moon rose as they waited.
