Lucia walked to the edge of the property that night. To the place where the shimmer was thinnest.
The moon was high and pale, casting long shadows across the grass. She had made this walk a hundred times, maybe a thousand. The path was worn into the earth now, a faint trail that only she and Ingrid ever noticed. The grass grew strange along its edges, taller in some places, stunted in others, like the ground itself couldn't decide what it wanted to be.
She stopped at the fence line.
The shimmer was there. She had never been able to see it properly, not the way Ingrid could, not the way Marcus was beginning to. But she could feel it. A pressure against her skin, like standing too close to a fire. The air was different here. Thicker. Charged.
And on the other side...
She could feel them. Not clearly, not faces or voices. Just presence. Hunger. Patience. The same things she had felt for years, growing stronger. They were waiting. They had been waiting for a long time.
Sometimes, late at night, she wondered what they saw when they looked at the orphanage. Did they see the building? The children? Or just the barrier, a wall of light keeping them from something they wanted?
The twins, she thought. They want the twins.
She had known it for years. Had known it since the night Leo left, when Ingrid had finally told her the truth. The twins weren't just orphans. They were something else. Something that creatures in the dark would kill to possess.
She stood there until her hands stopped shaking. Then she walked back to the orphanage.
The barrier would hold. For now.
But hearing what Darwin had done in the garden, the strength, the speed, the boy through the fence, had shaken her. She wasn't ready to tell him.
Let him be a child a little longer, she thought. Let him have a few more years of not knowing.
But the weak spots were growing. And the things on the other side were getting hungrier.
----
Marcus couldn't stop seeing things.
At first he thought it was his imagination. A shimmer at the edge of vision. A thinness in the air. But the more he paid attention, the more certain he became.
There was something around the property. Something invisible. And it was breaking.
It started small. He would be walking the grounds, doing chores, fetching water, helping Mrs. Hale with the garden, and he would feel a strange pull. Like something tugging at the corner of his attention. When he looked, there was nothing there. Just air. Just grass. Just the same old fence they had all walked past a thousand times.
But the air felt different in those places. Thinner. Like a sheet of parchment held up to candlelight, almost transparent, almost ready to tear.
He started mapping it in secret.
Late at night, after Darwin had fallen asleep, Marcus would slip out of bed and cross to the window. He had a piece of paper hidden behind the loose board near his bed: a rough sketch of the property, drawn from memory. Each time he found a new thin spot, he marked it with an X. Each time an old spot seemed to grow thinner, he darkened the mark.
The gap by the eastern fence. The thin spot near the well. The place behind the chapel where the protection disappeared entirely.
Twelve weak points now. There had been only three when he started.
He didn't know what it meant. Didn't know why he could see things that no one else seemed to notice. But he knew it was important. He knew it was wrong.
He kept his maps hidden under his mattress. And he kept watching.
----
One evening, he found Lucia in the library.
She was surrounded by old books, the kind with symbols on their spines that made his eyes hurt. A candle burned low on the table beside her, casting long shadows across the walls. She didn't look up when he entered.
Marcus stood in the doorway for a moment, watching her. Then he crossed to the chair across from hers and sat down.
Lucia turned a page. Still didn't look up.
"Can I ask you something?"
"It's late, Marcus. You should be in bed."
"I know. But I need to ask you something. And I think you're the only one who'll tell me the truth."
That made her pause. Her fingers stopped on the page, and for just a moment, her eyes flickered up to meet his. Then back down.
"What is it?"
Marcus took a breath. He'd been practicing this in his head for days, how to say it without sounding crazy. How to make her understand that he wasn't imagining things.
"There's something around this place," he said quietly. "Isn't there? Something we can't see."
The words hung in the air between them.
Lucia didn't look up. "The property has old foundations. Sometimes the ground settles strangely."
"I'm not talking about the ground."
"Then I don't know what you mean." She turned a page. Calm. Unbothered.
But Marcus had been watching people his whole life. And right now, Lucia's shoulders had gone rigid. Her fingers pressed too hard against the page.
"You looked up," he said.
"What?"
"When I said 'something we can't see.' You looked up. Just for a second. At the ceiling. Like you were checking something."
Lucia's hand stopped on the page.
"Go to bed, Marcus."
"The gap by the eastern fence," he said, not moving. "The thin spot near the well. The place behind the chapel where it disappears completely."
Now she looked at him. Really looked.
"What did you say?"
"Twelve weak points." He pulled a folded paper from his pocket: a rough map, hand-drawn, marked with X's and notes. "There were only three when I started counting."
Lucia stared at the map. Her face went carefully blank, the kind of blank that took effort.
"Where did you get this?"
"I made it."
"You made it." She set the paper down on the table, pushing it away from her like it might bite. "And where did you get the idea to make something like this?"
"I told you. I see things. Thin places in the air. Places where something is... wrong."
"You're twelve years old, Marcus. You have an active imagination. That's normal."
"This isn't imagination."
"It's late. You're tired. You've been reading too many of those old books in the-"
"You know I haven't." His voice was quiet but firm. "You know exactly what's on those shelves. You keep them locked. I've never touched them."
Lucia's jaw tightened.
"Go to bed."
"Not until you tell me the truth."
"There's nothing to tell."
"Then why won't you look at the map?"
Silence.
Marcus didn't move. Didn't look away. He had learned patience from watching her, from watching all of them. He could wait.
Lucia's hands were flat on the table now. Her breath came slow and controlled, like she was trying very hard not to react.
"You're not going to let this go, are you?"
"No."
Another long silence.
Then she laughed. Soft, tired, almost sad.
"Three months," she said. "I've been trying to hide this for three months. And you mapped it in, what? Weeks?"
"Six weeks."
She shook her head.
"You're too sharp for your own good. You know that?"
"Is it dangerous?"
Lucia didn't answer right away. She picked up the map again, studying it like she was seeing it for the first time.
"You shouldn't have found this," she said quietly. "You shouldn't be able to see any of this."
"But I can."
"I know." She folded the map carefully, her movements slow and deliberate. "And that changes things."
"What things? What does it mean?"
She met his eyes. For a moment, Marcus thought she might actually tell him. But then her expression closed off again, that careful blankness returning.
"It means you need to be more careful. It means you don't go near those weak spots. And it means..." She stopped herself. Shook her head. "It means you go to bed, Marcus."
"You're not going to tell me anything, are you?"
"I'm telling you what you need to know right now." She tucked the map into her pocket. Keeping it. "The rest... you'll learn when you're ready. Not before."
"How will you know when I'm ready?"
Something flickered across her face, almost a smile, but sadder.
"I'll know."
Marcus wanted to argue.
"Don't tell Darwin," she added.
"Why?"
"Because your brother has enough to carry. Even if he doesn't know what it is yet."
Marcus didn't fully understand that. But he nodded anyway.
He went to bed.
But he didn't stop mapping. And he didn't stop watching Lucia either, the way she sometimes paused before answering, like she already knew what he was going to say. The way her eyes would flicker to the door a moment before someone knocked.
Little things. Strange things.
He added them to a different list. One he kept only in his head
