The Parasite Rose

Chapter 18 — Testing

His hand stayed on my wrist longer than necessary.

We were in the study. The exchange. The knife was still on the blotter, the cut on my wrist still fresh, the blood still flowing. But he hadn't let go. His fingers were pressed against my pulse point—index, middle, ring—the way a doctor takes a reading, except his fingers were cold and his eyes were closed and he was counting something I couldn't see.

"Your pulse is faster," he said.

"I just gave you blood. Of course it's faster."

"It was fast before the exchange." He opened his eyes. Dark, depthless, the kind of black that swallowed light and gave nothing back. "It's been fast for three exchanges now. Baseline has shifted from sixty-eight to seventy-eight."

"You've been counting my pulse?"

"I count everything. Three centuries of observation—you learn to notice when a baseline moves." His thumb pressed against my wrist, not hard, just enough to hold the position. "Your resting heart rate has increased by fifteen percent in two weeks. That's not normal for a parasite adjusting to reduced output."

"Maybe I'm stressed."

"You've been stressed since the day you walked into this castle. Your pulse hasn't changed until now." He paused. "What's different?"

I pulled my wrist free. Pressed my thumb over the cut. The wound was closing—fast, faster than it should have, the skin knitting together with a speed that made me want to look away.

"Nothing's different," I said.

He studied me. Three seconds. Five. The silence was his weapon, the same way silence was mine. But his silence was different—it was patient, infinite, the silence of someone who had learned to wait centuries for answers and could wait centuries more.

"Sit down," he said.

"I'd rather stand."

"Sit."

I sat. The chair was leather, worn smooth by centuries of use, the arms polished to a dull shine. I kept my wrapped hands in my lap, my fingers curled, the bandages hiding the transparency that was spreading up my fingers like frost on glass.

Damian walked to the bookshelf. Not the main shelf—the one behind his desk, the one with the books that were too old and too dangerous for casual browsing. He pulled one down. Small, leather-bound, the cover cracked and faded, the pages yellowed at the edges. He set it on the desk between us.

"This is not the ancient text," he said. "The one with the torn pages. This is something else."

I looked at the book. It was old—older than the castle, older than the vampire kingdom, the kind of old that meant the leather had been cured before anyone alive today was born. The cover had no title. No markings. Just a blank expanse of brown leather, cracked and dry, the stitching frayed at the corners.

"Whose is it?" I asked.

"A parasite's." He opened it to a bookmarked page. "Three hundred years ago. Before thehunter found me. Before the silver sword. Before any of this." He pushed the book toward me. "Read."

I looked at the pages. The handwriting was small, cramped, the ink faded to a dull brown. The script was different from modern writing—the letters connected in ways that made them hard to parse, the words running together in a stream of consciousness that suggested the writer had been in a hurry.

I picked up the book. The pages were thin, fragile, the paper cracking at the edges where my fingers touched it. I held it carefully—the way you hold something that might disintegrate if you breathe on it wrong.

The first page was a header. A name—or what might have been a name. The letters were too faded to read clearly, but I could make out a shape that might have been "Elara." Below it, a date. Three hundred and twelve years ago.

I turned the page.

The text was in the old script, the letters connected, the words flowing. I read slowly, sounding out each word in my head, translating the archaic phrasing into something I could understand.

The symbiotic flow is bidirectional. Every exchange carries more than power. It carries memory, emotion, the substance of the self. The parasite does not merely take from the host—it gives. And what it gives is not power. It is life.

I stopped reading.

Read the sentence again.

The parasite does not merely take from the host—it gives.

"What does this mean?" I looked up.

Damian was watching me. His expression was the same as always—calm, measured, the face of someone who had already read the passage a hundred times and was waiting to see what I would do with it.

"It means what it says," he replied. "The exchange is bidirectional. You're not just outputting blood. You're outputting life."

"Life."

"Memories. Emotions. The substance of your cells. Everything that makes you—you." He paused. "The parasite is a bridge. It connects your biology to the recipient's. And in the process, it transfers not just power, but the raw material of existence."

I stared at the page. The words sat there, black on yellow, the handwriting cramped and urgent, the author's desperation visible in every stroke of the pen.

I've felt it. Every exchange. The memories that aren't mine. The emotions that come from nowhere. The sensation of losing something I can't name. The parasite takes and gives, and what it takes is always more than what it gives back.

I closed the book.

My hands were shaking. Not from the cold—my hands were warm now, the blood running hot through vessels that were getting thinner by the day. The shaking was from something else. Something that sat in my chest like a stone, heavy and immovable, the weight of a truth that I'd been circling around for weeks without ever looking at directly.

"Bidirectional," I said. "So when I give blood to you—to Knox—I'm not just giving power."

"You're giving pieces of yourself."

"Pieces of myself."

"Memories. Emotions. Life force." His voice was quiet, measured, the voice of someone delivering a diagnosis. "The parasite doesn't distinguish between what it takes and what it gives. It treats everything as currency."

I pushed the book back across the desk. My fingers left no prints on the leather—too thin, too transparent, the skin not solid enough to leave marks.

"You knew," I said. "You knew this when you started the exchanges."

"I suspected."

"You suspected. And you didn't tell me."

"I didn't have proof." He picked up the book. Held it in both hands, the leather cracked under his fingers. "The ancient text with the torn pages—I think it had the complete description. Someone tore those pages out deliberately. This notebook is a fragment. A parasite's personal account. Not authoritative."

"Not authoritative." I stood. The chair scraped against the floor. "You've been reading my pulse, counting my output, tracking my baseline—and you didn't think it was worth mentioning that every exchange might be killing me?"

"I didn't say it was killing you."

"You said it was transferring life force. That's the same thing."

"It's not." He set the book down. His voice was still calm, but there was something underneath it—a tightness, a tension, the kind of control that comes from holding something back. "Life force transfer doesn't necessarily mean death. It could mean... change."

"Change."

"The parasite is rewriting you. Every exchange. Your blood is being converted into something else—something that bridges the gap between you and the recipient. The transparency, the thinning skin, the altered heartbeat—these are side effects of the conversion."

"Side effects." My voice was flat. The** was gone—the voice that usually filled the silence with sarcasm and deflection was absent, replaced by something raw and exposed. "You're telling me my body is being rewritten, and you're calling it a side effect."

He looked at me. Dark eyes, steady, the candlelight reflected in them like two small flames. "I'm telling you that I don't know what's happening to you. I have fragments. Pieces. A notebook written three hundred years ago by someone who may or may not have understood what she was experiencing." He paused. "I'm telling you what I know. Not what I wish I knew."

I looked at his hands. On the desk, resting on the notebook, the silver ring catching the light. His fingers were steady—no shaking, no tremor, the hands of someone who had been still for three centuries and had forgotten what it felt like to be out of control.

My hands were shaking. I shoved them into my pockets.

"What happened to her?" I asked. "The parasite who wrote this."

He was quiet for a moment. "She disappeared. Around the time thehunter began their campaigns. I don't know what happened to her."

"Disappeared."

"Many parasites did. The records are incomplete." He picked up the notebook. Opened it to a page near the end. "This is the last entry."

I looked at the page. The handwriting was different here—shaky, the letters uneven, the ink smeared in places. The author had been in a hurry. Or in pain.

I can feel it now. The conversion. It's not a process—it's a destination. Every exchange brings me closer to something I can't see. My hands are fading. My reflection is wrong. I keep smiling when I'm not smiling. Something else is looking through my eyes.

I read the last line twice. Then I closed the book.

"The smile," I said. My voice was barely audible. "In the mirror."

Damian looked at me. "What?"

"Nothing." I picked up the knife from the blotter. Slid it into my pocket. The blade was warm from the candle, the handle smooth under my transparent fingers. "We're done."

I walked to the door. His voice followed me—not loud, not commanding, just present.

"Whatever you're hiding," he said, "it will eventually surface."

"That's what you said last time."

"Because it's still true."

I stopped at the door. My hand was on the frame—my left hand, wrapped, the bandages hiding the transparency. I looked at the wood grain, the old scratches, the places where centuries of use had worn the surface smooth.

"If you already know what's happening to me," I said, "why are you asking?"

Silence. Three seconds. Five.

"Because I want to hear you say it," he said.

I didn't turn around. I didn't need to. His voice was enough—the weight of it, the careful precision, the three centuries of restraint compressed into a sentence that said more than he probably intended.

I left the study. The door closed behind me. The corridor was dark, the castle quiet, the only sound the distant drip of water from somewhere in the walls.

I walked to my room. Locked the door. Sat on the bed. Unwrapped my left hand.

The transparency had spread. The index and middle fingers were fully transparent—the light from the candle passing through them like glass. The ring finger was halfway. The pinky was three-quarters. The palm was starting—the skin thinning, the veins visible, the bones casting shadows inside my own hand.

I held it up. The candlelight went through. All the way through, from back to front, the flame visible between my fingers like a light seen through a stained-glass window.

Bidirectional. Every exchange. The memories that aren't mine. The emotions that come from nowhere. The sensation of losing something I can't name.

I lowered my hand. Picked up the journal from under the mattress. Opened it to the page with the calculations—the columns of numbers, the estimates, the countdown.

I wrote two words at the bottom.

Bidirectional.

Then I drew a line under it. A thin, straight line, the kind that separates the before from the after. The known from the unknown. The girl who was disappearing from the girl who hadn't noticed yet.

I closed the journal. Put it under the mattress. Lay back on the bed and stared at the ceiling, my transparent hand resting on my chest, the candle burning low, the shadows growing longer as the wax ran out.

The candle went out. The room went dark. And in the darkness, I could feel my hand on my chest—warm, still warm, the blood still moving through veins that were getting thinner, the heartbeat still steady, the body still counting.

But the counting was getting faster. And the numbers were getting smaller.

And somewhere in the space between what I was and what I was becoming, the parasite was busy—rewriting, converting, transferring pieces of me to people who didn't know they were carrying parts of a girl who was slowly fading away.

I pressed my transparent hand harder against my chest. Felt the heartbeat through the thin skin, through the fading flesh, through the bones that were still there, still solid, still mine.

For now.
