The cake sat in the center of the kitchen table, sixteen candles flickering in the afternoon light.

Luna stared at the flames. Something felt off. Wrong. The air tasted sharp. Metallic.

"Make a wish, mija," her mother said from across the table.

Luna leaned forward. The candles seemed too bright. She could hear them. Actually hear them. The tiny hiss and crackle of wax melting. The whisper of flame consuming oxygen.

When had she started hearing things like that?

She closed her eyes and blew.

The room erupted in cheers. Her little brother Diego whooped. Her father clapped. Miguel squeezed her shoulder from where he stood behind her chair, and several of her friends from school laughed and whistled.

The touch burned.

Luna flinched. Just slightly. But Miguel noticed.

"You okay?" he whispered.

She forced a smile and looked up at him. "Yeah. Just startled me."

Lie. She wasn't startled. His hand on her shoulder felt like heat. Like pressure. Like too much.

Her mother started cutting the cake. Chocolate with vanilla frosting. Luna's favorite since she was six.

But when the plate landed in front of her, the smell hit like a wave.

Too sweet. Too strong. Overwhelming.

She could identify everything. Flour. Sugar. Cocoa powder. Eggs. Butter. Vanilla extract. Even the baking soda. She could smell all of it separately and together and it was too much.

"Luna?" Her friend Jenna leaned across the table. "Girl, you look pale. You feeling sick?"

"I'm fine."

"You sure? Because you look like you're about to pass out."

"I'm fine," Luna repeated. Her voice came out sharper than she intended.

Jenna held up her hands. "Okay, okay. Just checking."

Luna picked up her fork. Her wrist itched. She scratched at it absently with her other hand, then froze.

Something was wrong with her skin.

She pulled her hand into her lap under the table and twisted her wrist toward the light streaming through the kitchen window.

A mark.

Faint silver lines. Barely visible. But there. And they were getting brighter.

The pattern looked like a crescent moon with shadow bleeding into it. Something sat at the center. An eye maybe? She couldn't tell. It was too small. Too faint.

But it was glowing.

On her wrist.

Growing brighter with each second.

"Luna."

Her father's voice. Low. Serious. Not his birthday party voice.

She looked up.

He wasn't smiling anymore. He was staring at her lap. At where her hands were hidden.

"Show me your wrist."

The table went quiet. All conversation stopped. Diego stopped eating. Miguel straightened behind her. Jenna and the other friends looked between Luna and her father with confusion written across their faces.

Luna's throat tightened. "What?"

"Your wrist, Luna. Put it on the table. Now."

Her hands were shaking. She could feel them trembling as she slowly lifted her right hand and placed it palm down on the tablecloth.

The mark pulsed with pale silver light.

Her mother made a sound. Sharp and broken. Like someone had punched her.

Jenna gasped. "What is that? Is that a tattoo? When did you get a tattoo?"

Miguel leaned forward, his hand reaching toward her wrist. "Luna, what—"

"Don't touch her." Her father's voice cracked like a whip.

Miguel jerked his hand back.

"Everyone who doesn't live in this house needs to leave. Now."

"Mr. Eclipse, what's going on?" Jenna stood up, her chair scraping against the floor. "Is Luna okay?"

"She's fine. But you need to go. All of you. Now."

"But we just got here. We haven't even finished—"

"Now."

The word left no room for argument.

Jenna grabbed her purse. The other friends shuffled toward the door, casting worried glances back at Luna. Miguel didn't move.

"Miguel." Her father turned to face him. "You too."

"No." Miguel's hand landed on Luna's shoulder again. Gentler this time. "I'm not leaving her."

"You don't have a choice."

"Yes, I do. I'm her boyfriend. If something's wrong, I'm staying."

"Miguel, please." Her mother's voice cracked. There were tears on her cheeks. When had she started crying? "Please just go. We'll explain everything to Luna. She'll call you later."

"Not until someone tells me what that thing on her wrist is."

Luna's wrist burned. The light grew brighter. She could feel it now. Not just see it. A pulse beneath her skin. Matching her heartbeat. Or controlling it. She couldn't tell which.

"Papá?" Her voice came out small. Young. Scared.

He moved to her side and knelt beside her chair. His hand hovered over hers but didn't touch.

"How long have you felt different?"

"Since I woke up this morning. Everything's been weird. Loud. Bright. Strong."

"Your senses?"

She nodded.

"Hearing things you shouldn't hear? Smelling things too clearly?"

Another nod.

Her mother pressed her hand to her mouth. "Dios mío. She's only sixteen. It's too early. She shouldn't have been marked until at least eighteen."

"It's happening anyway, Elena."

"What's happening?" Miguel's voice rose. "Someone explain what's happening to her right now."

Her father stood. Slowly. He looked at Miguel. Really looked at him. When he spoke, every word carried weight.

"Luna is marked. She's a wolf shifter. And she can't stay here anymore."

Silence.

Complete silence.

Miguel laughed. It sounded wrong. Forced. "That's not funny, Mr. Eclipse."

"I'm not joking."

"Wolf shifter? Like werewolves? You're saying Luna is a werewolf?"

"Not exactly. But close enough. The mark means she's changing. Her body. Her instincts. Everything. If she doesn't learn to control it, she'll be dangerous. To herself. To everyone around her."

"This is insane." Miguel backed away from the table. From Luna. "You're all insane."

"Miguel." Luna tried to stand. Her legs wobbled. "Please."

"Stay away from me."

The words hit like a slap.

"Miguel, I'm still me. I'm still—"

"You're glowing. Your wrist is literally glowing. That's not normal. That's not human."

"I know. I don't understand it either. But I'm still me. I'm still Luna."

"Are you?" He looked at her like he'd never seen her before. "Because the Luna I know doesn't have weird marks that appear out of nowhere. The Luna I know is normal."

"I thought I was normal too."

Her father moved between them. "You need to leave now, Miguel. For your own safety."

"My safety?"

"Luna doesn't have control yet. If you stay, if you push her, she could hurt you without meaning to. The mark responds to emotion. To stress. Right now she's terrified and confused and you being here is making it worse."

Miguel stared at Luna. She could see the fear in his eyes. The disbelief. The horror.

Then he turned and walked out.

The front door slammed.

Luna's wrist exploded with heat. The mark blazed so bright she had to close her eyes against it.

She heard her mother cry out. Heard Diego run from the room. Heard her father curse under his breath.

"Luna, listen to me." Her father's voice cut through the pain. "You need to breathe. Slow and steady. The mark responds to panic. If you panic, it gets stronger. Breathe."

She tried. She pulled air into her lungs. Once. Twice. Three times.

The pain eased. Slightly.

"Good. Keep going. In and out. Focus on my voice."

She did. She focused on breathing. On her father's steady instructions. On anything except the fire burning up her arm.

Slowly, the light dimmed.

When she finally opened her eyes, her mother was sitting across from her with tears streaming down her face. Diego peeked around the doorway, his eyes huge.

"I don't understand," Luna whispered. "What's happening to me?"

"You've been marked by the moon goddess," her father said. "It's rare. It skips generations sometimes. My grandmother had it. Your mother's abuela had it. We knew it might happen to you. But we hoped. We prayed it wouldn't."

"Marked for what?"

"To be a wolf shifter. To attend Silverwood Academy. To learn control and become part of the pack world."

"There's a pack world?"

"There's a whole society you never knew existed. Wolves living among humans. Packs with territories. Academies that train marked ones. Laws. Hierarchies. Everything."

Luna looked at the mark on her wrist. The light had faded to a dim glow. The pattern was clearer now. A crescent moon broken by shadow. An eye at the center.

"When do I have to leave?"

Her mother sobbed.

"Tonight," her father said quietly. "They'll come for you tonight. You need to pack. Not much. They'll provide everything you need at the academy."

"Tonight? But I haven't said goodbye to anyone. I haven't finished school. I haven't—"

"None of that matters now. The mark appeared. That means the change is starting. You have to go before it gets worse."

"What if I refuse?"

"Then you'll lose control. You'll shift without meaning to. You'll hurt someone. Maybe kill someone. Is that what you want?"

"No."

"Then you go to Silverwood. You learn control. And maybe, if you're lucky, you can come home someday."

Maybe.

The word hung in the air like smoke.

"I need to be alone," Luna said. "I need to think."

"You have until sunset. That's when they'll arrive."

She stood. Her legs still felt shaky, but she managed to walk. Out of the kitchen. Through the living room. Up the stairs to her bedroom.

She closed the door and locked it.

Her room looked the same as it had this morning. Posters on the walls. Clothes on the floor. Books stacked on her desk. Everything normal. Everything familiar.

Everything she was leaving behind.

Luna walked to her window and looked out at the street below.

A figure stood on the sidewalk.

Miguel.

He was staring up at her window. Just standing there. Not moving. His hands were in his pockets. His shoulders were hunched.

Even from here, even through the glass, she could see his expression.

Confusion. Fear. Hurt.

But something else too.

Something she couldn't name.

He lifted one hand. A small wave. Hesitant.

Luna pressed her palm against the window.

The mark on her wrist pulsed.

And Miguel flinched.

Like he'd felt it.

Like he'd sensed the change in her from all the way down there.

Their eyes locked.

Neither of them moved.
