Broken glass crunched beneath Val's boots as she passed under the graceful arch of the underpass. The sidewalk stank of stale urine and something rotting. On one side was a makeshift wire fence, blocking the way into a construction area where a mound of sand waited to be spread. On the other, close to where she walked, was what looked like a bricked-up doorway. Below it, Val saw the stump of a tree, its roots digging deep into the concrete.

"The tree." Val kicked the stump softly. The wood was wet and dark with filth, but the roots sank down into the concrete sidewalk, as though they stretched past the tunnels and pipes, worming their way into some secret, rich soil. She wondered if this was the same tree that bloomed with pale fruit.

It was an eerie thing to see a stump here, nestled up against a building as if they were kin. But perhaps no eerier than the idea that she'd fallen into a fairy tale. In a video game, there would have been some pixilated storm of color and maybe even an on-screen message warning her that she was leaving the real world behind. Portal to Faerieland. Do you want to go through? Y/N.

Val knelt down and rapped three times on the stump. The wet wood barely made a sound under her knuckles. A spider scuttled out toward the street.

A sharp noise made Val look up. A fracture appeared in the stone above the stump, as though something had struck it. She stood and reached out to run her finger across the line, but as she touched the wall, patches of stone cracked and fell away, until there was a rough doorframe.

She stepped through onto the stairwell, steps extending up and down from the landing. When she looked back, the wall was solid. A sudden burst of terror nearly overwhelmed her and only pain held her in place.

Trip Trap.

"Hello?" she called up the steps. It hurt to move her mouth.

Trip Trap.

The troll appeared on the landing.

Who's trip trapping over my bridge?

"Most people would have come sooner." His rough, gravelly voice filled the stairway. "How your mouth must hurt to bring you here at last."

"It wasn't so bad," she said, trying not to wince.

"Come up, little liar." Ravus turned and walked back to his rooms. She hurried up the dusty stairs.

The large loftlike space flickered with fat candles set on the floor, their glow making her shadow jump on the walls, huge and terrible. Trains rumbled above them and cold air rushed in through covered windows.

"Here." In the palm of one six-fingered hand, he held a small, white stone. "Suck on it."

She snatched the stone and popped it in her mouth, in enough pain not to question him. It felt cool on her tongue and tasted like salt at first and then like nothing at all. The pain abated slowly and with it, the last of the nausea, but she found exhaustion taking its place. "What do you want me to do?" she asked, pushing the rock into her cheek with her tongue so she could talk.

"For now, you can shelve a few books." Turning, he went to his desk and began to strain the liquid from a small copper pot thick with sticks and leaves. "There may be an order to them, but since I have lost the understanding of it, I don't expect you to find one. Put them where they will fit."

Val lifted one of the volumes off a dusty pile.

The book was heavy, the leather on it cracked and worn along the binding. She flipped it open. The pages were hand lettered and there were water-color and ink drawings of plants on most of the pages. "Amaranth," she read silently. "Weave it into a crown to speed the healing of the wearer. If worn as a wreath, confers invisibility instead." She closed the book and pushed it into the plywood and brick shelves.

Val rolled the stone around in her mouth like a candy as she put away the troll's scattered tomes. She took in the mishmash of moth-eaten army blankets, stained carpet, and ripped garbage bags that served as curtains not even the outside streetlights could pierce. A dainty flowered teacup, half full of a brackish liquid, rested beside a ripped leather chair. The idea of the troll holding the delicate cup in his claws made her snort with laughter.

"To know your target's weakness, that is the intuitive genius of great liars," said the troll without looking up. His voice was dry. "Though the Folk differ greatly, one from another and from place to place, we are alike in this: We cannot outright speak what is untrue. I find myself fascinated by lies, however, even to the point of wanting to believe them."

She didn't reply.

"Do you consider yourself skilled in lying?" he asked.

"Not really," Val said. "I'm more of an accomplished sucker."

He said nothing to that.

Picking up another book, Val noticed the glass sword hanging on the wall. The blade was newly cleaned and looking through it, she could see the stone, each pit in the rock magnified and distorted as though it was under water.

"Is it made from spun sugar?" His voice was close by and she realized how long she'd been staring at the sword. "Ice? Crystal? Glass? That's what you're wondering, isn't it? How something that looks so fragile is so hard to break?"

"I was just thinking how beautiful it was," Val said.

"It's a cursed thing."

"Cursed?" Val echoed.

"It failed a dear friend of mine and cost him his life." He ran one hooked nail down the length of it. "A better blade might have stopped his opponent."

"Who… who was his opponent?" she asked.

"I was," the troll said.

"Oh." Val could think of no reply. Although he seemed calm now, even kind, she heard the warning in his words. She thought of something her mother had told her when she'd finally broken up with one of her most dysfunctional boyfriends. When a man tells you he's going to hurt you, believe it. They always warn you and they're always right. Val pushed the words out of her head; she didn't want any of her mother's advice.

The troll walked back to the table and picked up three waxed and stoppered beer bottles. Through the amber glass she couldn't see the color of the contents, but the idea that it might be that very same amber sand that ran through her veins the night before made her skin thrill with possibility.

"The first delivery will be in Washington Square Park, to a trio of fey there." One hooked nail pointed to a map of the five boroughs and most of New York and New Jersey taped on the wall. She walked closer to it, noticing for the first time that there were thin black pins stuck into various points along the surface. "The second can be left outside of an abandoned building, here. That… recipient may not wish to show himself. I want you to take the third to an abandoned park, here." The troll seemed to be indicating a street in Williamsburg. "There are small grassy hills, close to the rocks and the water. The creature that you seek will wait for you at the river's edge."

"What are the pins for?" Val asked.

He gave the map a quick sideways look and seemed to hesitate before speaking again. "Deaths. It isn't unusual for the Folk to die in cities—most of us here are in exile or in hiding from other fey. Living so close to so much iron is dangerous. One would only do it for the protection it affords. But these deaths are different. I'm trying to puzzle them out."

"What am I delivering?"

"Medicine," he said. "Useless to you, but it eases the pain of the Folk exposed to so much iron."

"Am I suppose to collect anything from them?"

"Don't concern yourself with that," said the troll.

"Look," Val said. "I'm not trying to be difficult, but I never lived in New York before. I mean, I've been up here for things and I've walked around the Village, but I can't find all these places with a glance at a map."

He laughed. "Of course not. Had you hair, I would give you three knots, one for each delivery, but since you don't, give me your hand."
