Training began before dawn the next morning. Grey woke me by pulling the blanket off my cot and dropping a pair of running shoes on my chest. They were my size. I didn't ask how he knew.
"We start with speed," he said. "Everything else flows from that. If you can't run, you can't hunt. If you can't hunt, you can't feed. If you can't feed, the hunger takes over and you become exactly what the Order expects you to be."
We went to a stretch of abandoned industrial road on the far south side, past the old steel mills, where the pavement was cracked and the streetlights were dark and there was nothing to hit but chain-link fences and burned-out factories. The sky was still black. The air was cold enough to see your breath.
"Your muscle fibers have changed. They're denser now. More efficient. The fast-twitch fibers in particular. Under full shift you'll run on four legs, but you can access some of that speed in human form if you learn how. It's about stride."
He demonstrated. He was an old man in a ragged coat, but when he ran, the age fell away. His legs ate ground in long, low strides that didn't match the rhythm of a human gait. He covered fifty yards in under four seconds and stopped without slowing down, just planted his feet and was still.
"Your turn."
I ran. It felt normal at first. My usual pace. My usual stride. Grey watched for thirty seconds, then held up a hand.
"Stop. You're running like a human."
"I am a human."
"No. You're not. Not anymore. Your joints can take more impact than you think. Your tendons are stronger. Your lungs process oxygen differently. You're holding back because your brain hasn't caught up to your body. Stop thinking and let your legs find their own rhythm."
I tried again. And again. And again. Each time Grey corrected something different. The angle of my foot strike. The length of my stride. The way I held my arms. The way I breathed. It was like learning to walk all over again, except the body I was learning to walk in kept changing, kept revealing new capabilities I didn't know it had.
On the fifth try, I hit a stride I'd never felt before. My legs opened up. The impact that would have shattered a human shin was absorbed by tendons that felt like steel cables. The pavement blurred under me. The wind screamed past my ears. Everything that wasn't directly in front of me became a smear of gray and black.
I ran for six seconds. When I stopped, I was four hundred and twenty feet from where I'd started. Grey checked a stopwatch I hadn't seen him produce.
"Forty-one miles per hour. Roughly. The stopwatch isn't calibrated for this."
I was lying on the gravel by the side of the road. My lungs were heaving. My legs were screaming. Every muscle fiber I possessed felt like it had been set on fire and then beaten with a hammer.
Forty-one miles an hour. The world record for human sprinting was just under twenty-eight. I'd just beaten it by thirteen miles an hour on an abandoned road in south Chicago while an ancient wolf-man timed me with a drugstore stopwatch.
I started laughing. I couldn't help it. The absurdity of it was too much. Three months ago I'd been a security guard who got winded walking up three flights of stairs. Now I was outrunning cars on the expressway.
Grey let me laugh. When I stopped, he was looking at me with an expression I hadn't seen on his face before. Quiet approval. It was gone almost immediately, replaced by his usual clinical detachment, but I'd seen it.
"Good," he said. "That's the baseline. Tomorrow we work on endurance. The day after, agility. After that, we start the strength training. Partial shifts under controlled conditions. Learning to access the change without losing yourself."
We trained for three more hours as the sun came up. Sprinting intervals. Recovery breathing. Core exercises designed for a body that healed faster than it could be damaged. By the end, I was exhausted in a way I'd never been exhausted before, every cell in my body pushed past its limits and then pushed again.
But underneath the exhaustion was something else. Something I hadn't felt in years. Maybe ever. Physical confidence. The knowledge that my body could do things. Extraordinary things. That I wasn't just a victim of whatever Aldric had done to me. I was becoming something. Something powerful. Something dangerous.
It terrified me. It also felt incredible.
We walked back to the hideout as the city woke up around us. I was sore and tired and hungry in ways that went deeper than food, but there was a lightness in my chest that hadn't been there before. Hope, maybe. Or at least the possibility of hope.
The feeling lasted until we reached the building.
The door was slightly ajar.
Grey stopped dead. His whole body went rigid in a way I was learning to recognize. Hunter's stillness. Predator's focus. He raised a hand, palm flat: don't move.
He approached the door without making a sound. His footfalls were silent on the concrete steps. His breathing had dropped to something nearly imperceptible. He pushed the door open with two fingers and slipped inside.
I waited. Ten seconds. Twenty. Thirty. The street was empty. The morning light was gray and cold. A car passed at the end of the block without slowing.
Grey reappeared in the doorway. His face was unreadable.
"It's clear. They're gone."
I followed him inside. The hideout looked the same as we'd left it. Books on the shelves. Weapons on the racks. Maps on the walls. Nothing seemed out of place. Nothing seemed taken.
"Are you sure someone was here?"
Grey pointed at the table in the center of the room. There was a single silver coin on it, polished to a mirror shine. It hadn't been there when we left.
He picked it up between thumb and forefinger, holding it away from his skin as much as possible. Even that brief contact left a faint red mark. I remembered what he'd said about silver. How it burned like acid. How it was the only thing that could kill us permanently.
"Caleb," Grey said quietly. "Do you know what this is?"
"No."
"It's a calling card. Clan Nacht. The oldest wolf clan in North America. They've operated out of Chicago for over a century. Organized crime, mostly. The underworld is easier to navigate when you can smell a lie and heal a bullet wound in sixty seconds."
He set the coin back on the table and wiped his fingers on his coat.
"This is Viktor Thorne's territory. He's been First Fang of Clan Nacht for about two hundred years. He doesn't leave calling cards for new wolves unless he has a reason. A very specific reason."
"What reason?"
Grey looked at me, and the expression on his face was one I was learning to dread. It was the look he got when he was about to tell me something that would make everything worse.
"Aldric was Nacht's eldest. Viktor's grandsire, four generations removed. When Aldric bit you, he didn't just make you a wolf. He made you part of a lineage. A bloodline that goes back centuries. Viktor cares about bloodlines the way kings care about succession. You're not just a new wolf, Caleb. You're an heir."
I stared at the coin. It gleamed on the table like a promise made of poison.
"An heir to what?"
"That's the question Viktor wants to answer," Grey said. "And he's not the kind of person who takes no for an answer."
That night I dreamed of a man in a black suit. He was standing in the doorway of every foster home I'd ever lived in, watching me with eyes that were cold and patient and utterly without mercy. He never spoke. He never moved. He just stood there and smiled while the families I'd tried to belong to packed my things and sent me away.
When I woke up, I couldn't remember if it was a dream or a memory.
