THE FIRST SHIFT

Nyx woke to her own body betraying her.

The sensation started at her fingertips at first light—a burning beneath the skin like carbonation mixed with electricity, like something alive was trying to escape the cage of her body. She gasped and pressed her hands against her chest, but the feeling only spread. Her bones were changing. Not dramatically, not yet, but she could feel the subtle restructuring happening at the cellular level—her frame remembering that it had been designed for more than human shape.

And worst of all, through the haze of awakening panic, she felt *his* essence inside her—the fragment she'd absorbed at the wedding kiss when he held her face and every wall between them had dissolved for one perfect, terrifying moment. That piece of Caelan Voss, that stolen Alpha fragment, was responding to her distress by surging forward like a tide with no moon to control it.

*No, no, no,* Nyx thought desperately, drawing on twenty-two years of control and suppression and self-denial. *Stay human. Stay hidden. Stay alive.*

But the stolen wolf essence had other ideas entirely.

"I need you to get out. Now. This moment." Nyx's voice cracked like old paper.

Caelan had been awake already—watching her sleep in that unsettling way he'd developed since the bonding, as if he was afraid she'd disappear if he closed his eyes. He shifted from the bed with liquid grace and was beside her in seconds. "What's wrong? What do you feel?"

"Out. Get out. Please." She pushed him away, or tried to, but her hands felt strange and oversized even in human form.

Caelan was an Alpha, though, and his instinct was to move toward threats, not away from them. He grabbed her shoulders and forced her to look at him. "Tell me what—"

His touch did it. The moment his skin met hers, the stolen fragment of his wolf erupted.

Nyx screamed and twisted away so violently she fell off the bed, her body convulsing as the shift began. But this wasn't like her small shifts—the stolen face of Petra, the borrowed voice she'd practiced in the forest as a child. This was a full transformation, and it was happening without her permission, driven by an Alpha essence that had decided it was time to emerge and claim its space in this world. Her bones cracked. Not metaphorically—literally cracked and restructured and reformed into shapes they'd never held before. Her skin stretched and split slightly at the seams as fur began to emerge. But not her fur, because Nyx didn't have a wolf form. This was *his* fur. Silver-black. Scarred. *Caelan's* fur.

She was becoming him.

The shift convulsed through her body like a seizure. Nyx felt her face elongate, her jaw reshape, her teeth sharpen. Her consciousness split between human and wolf in a way that should have been impossible, like trying to exist in two places simultaneously. She crashed through the balcony doors without meaning to—her expanding body was simply too large for the frame now, too massive, too *wrong*.

Cold mountain air hit her lupine face and Nyx gasped, trying to remember how to breathe in a form that wasn't hers but was wearing her consciousness like an ill-fitting coat. She was enormous. The paws that touched the stone balcony were the size of dinner plates. When she looked down at her fur, she saw the distinctive silver-black pattern, the exact scars along the left foreleg, the precise configuration of muscle and bone that belonged to Caelan Voss and should never, ever belong to anyone else.

Inside her hybrid consciousness, part wolf and part Skinwalker, Nyx felt the monster that lived in the Alpha form. Caelan's wolf was roaring—but not in anger, not in fear. In something like *joy*. The beast knew what she was, knew that she was something that *should not be*, and it didn't care one bit. Animals didn't operate on three thousand years of genetic programming and divine mandate. They operated on one simple, irrevocable truth: she was *his*, and the wolf would keep her regardless of what species she was or what the Goddess demanded.

That terrified Nyx more than anything else possibly could.

She shifted back, her body rejecting the stolen form with a violence that bent her double. It was agony going both directions—the bones resetting, the skin reknitting, the consciousness rejoining into a single, fracturing point. She collapsed on the balcony stones, naked and gasping and shaking so hard her teeth chattered. Caelan caught her before she hit the ground, pulling her against his chest.

"Don't look," she whispered.

But of course he looked. Caelan tilted her chin up and examined her eyes in the dawn light. The silver was spreading through her irises like frost on glass. Not just a reflection of his color now, but *his* silver, threading through her brown like cracks in porcelain. His mark, written in her eyes where everyone would see it.

"We need to cover this. Now. Before anyone—" Nyx tried to pull away, but Caelan held her close.

"You shifted," he said quietly. "You didn't just copy a form. You shifted. Nyx, wolves don't do that. Shapeshifters don't exist in nature—"

"I couldn't stop it," Nyx cut in desperately.

"Only in the old texts," Caelan continued as if she hadn't spoken. "Only in stories about the First Kind. About the Skinwalkers."

Nyx pulled on his jacket and hugged herself. The mountain wind was freezing, but the cold was nothing compared to the chill of his understanding spreading through the tether like ice water. "I didn't want this. I didn't mean to—"

"You can become anyone," Caelan said quietly. "Any wolf. Any shape."

"I can copy what I touch," Nyx admitted. The truth was already out like blood from an opened vein. She had nothing left to hide. "It requires direct contact. I can hold it for a while, but it's temporary. And I can only do it with living things. I don't create a new person. I just... borrow their shape. Their voice. Their surface memories."

"You absorbed me," Caelan said. "During the bonding kiss. When we merged—you took a piece of me."

"Yes."

"And now you can shift into my wolf whenever you want. You can wear my face. Wear my body."

"I didn't want—"

"I know," he said, grabbing her face gently, forcing her to meet his eyes. "But you can. And that makes you the most powerful weapon that could possibly exist inside this fortress. And the most hunted."

Through the tether, understanding flooded between them like a breaking dam: whatever she was, whatever the Skinwalker ability truly entailed, it was more dangerous than either of them had imagined. More dangerous than forbidden magic or ancient prophecies. More dangerous than a creature that shouldn't exist. Because a creature that can become anyone is a creature that can infiltrate anywhere. A creature that can lie so perfectly that even the tether wouldn't catch the deception, because the deception would be written into her very cells.

If the wrong people found out what she could do—what she could *really* do—they wouldn't kill her out of fear. They would try to *use* her. And in that moment, watching the sunrise paint the volcanic peaks gold and red and terrible, Nyx understood that the tether binding her to Caelan wasn't just a cosmic accident anymore. It was the only thing stan

ding between her and that future.
