The rain had barely dried on the sidewalks when Emily Carter stood at the base of Knight Enterprises Tower. Fifty floors of glass and steel rose into the clouds like a blade, catching the morning light and scattering it across the city. The building didn’t just look powerful—it radiated it.

And today, she was walking inside.

Her fingers tightened around the strap of her handbag as she craned her neck, trying not to gape like a tourist. She’d seen skyscrapers before. She’d seen office towers. But this? This was a fortress. And behind its mirrored windows sat the man she’d been warned about—the billionaire who broke assistants like twigs and tossed them away without a second thought.

Please don’t do it, her roommate Jenna had said last night, watching her iron the single decent blouse she owned. You’ll last two weeks, tops. Everyone says he’s impossible.

But two weeks at Knight Enterprises paid what she’d make in three months at her old café job. Impossible or not, she couldn’t afford to walk away.

Emily drew in a shaky breath and stepped inside.

The lobby looked more like a five-star hotel than an office building. Marble floors gleamed under her heels, an abstract sculpture stretched toward the ceiling, and sleek men and women in tailored suits swept past without so much as a glance at her. She felt like an impostor already.

At the reception desk, a woman in a black blazer looked up. “Name?”

“Emily Carter. I’m—uh—the new assistant. Mr. Knight’s assistant.”

The woman’s eyes flicked over her quickly, assessing everything from the scuffed heels to the nervous bite of her lip. “You’re brave,” she said, picking up the phone. “Or stupid. Not sure which yet.”

Emily’s cheeks warmed.

A few moments later, she was ushered toward the private elevator. Private. Of course. He wouldn’t bother with the same elevators as everyone else. The receptionist pressed the button for her and gave a tight smile. “Good luck.”

The doors slid open, and Emily stepped inside, heart hammering.

The elevator rose smoothly, but her nerves bounced like a roller coaster. She replayed what she’d researched last night: Alexander Knight. Thirty-two years old. Self-made billionaire. Founded Knight Enterprises at twenty-four, now one of the fastest-growing investment firms in the country. Single. No scandals—at least, none that had ever been proven.

The doors opened on the fiftieth floor. Silence met her, broken only by the faint hum of air-conditioning. The entire top floor was his.

A sleek, open office stretched before her—minimalist furniture, dark wood, leather, and glass. A view of the city sprawled through floor-to-ceiling windows. For a moment, she thought the office was empty. Then she saw him.

He stood with his back to her, hands clasped behind him, staring out over the city as if it belonged to him. His suit was black, cut perfectly to his broad shoulders and lean frame. His posture screamed control.

Emily swallowed hard.

“Mr. Knight?” Her voice was small, uncertain.

He turned.

Her first thought was that he was beautiful in the kind of way that hurt. Sharp cheekbones, dark hair slicked back with ruthless precision, eyes the color of storm clouds. His jaw was strong, his lips unsmiling, every detail of him perfectly carved and entirely unapproachable.

Her second thought was that he was looking at her like she was already wasting his time.

“You’re late.” His voice was low, smooth, and it carried across the room like smoke.

Emily’s eyes flicked to her watch. Nine o’clock exactly. “I—I thought—”

“I said nine,” he cut in, stepping closer, “which means you should have been here before nine. Waiting. Ready.”

Her throat tightened. “I’m sorry.”

He studied her like a hawk sizing up prey. “You’re the new assistant?”

“Yes.” She managed to find a thread of firmness in her voice. “Emily Carter.”

He didn’t offer his hand. Instead, he turned and walked toward his desk. “If you want to last longer than the last one, don’t apologize for things you can’t change. Anticipate them.”

Her pulse skipped. The last one?

He sank into the leather chair behind his desk and gestured at the folder neatly placed in front of him. “Sit.”

Emily obeyed, perching on the edge of the chair opposite him.

“This,” he said, tapping the folder, “is your life for as long as you work for me. My schedule. My meetings. My travel. My preferences. You will memorize it.”

She nodded quickly.

“You will answer my calls immediately. If I say I need something, you’ll already know what it is. You will not argue. You will not hesitate. Do you understand?”

Emily’s lips parted. Every instinct told her to nod, to agree, to survive. But something stubborn flared instead. “I’ll do my best, Mr. Knight.”

His gaze sharpened. “Your best isn’t enough. Either you do it, or you don’t.”

The air between them thickened. Emily’s stomach twisted, but she lifted her chin. “Then I’ll do it.”

For the first time, something flickered across his face—not a smile, but a faint curve of intrigue, gone almost before it appeared.

“Good.” He leaned back, steepling his fingers. “Tell me, Emily Carter—why are you here?”

The question caught her off guard. “Because… you needed an assistant.”

His eyes narrowed, as if dissecting her words. “No. That’s why you’re in this building. Why are you here? In this chair. In front of me.”

Her breath caught. She could lie. She could tell him what he wanted to hear. But the truth slipped out instead. “Because I need the money.”

A dangerous pause. Then, slowly, his lips curved into something that might have been a smile—or a threat.

“At least you’re honest.”

The rest of the day was a blur of impossible tasks.

Fetch a list of contacts from a server buried three floors down. Call Tokyo at midnight their time. Memorize the faces of three board members she’d never met. At one point, he dismissed her with nothing but a wave of his hand, only to call her back two minutes later to test if she remembered the details of his schedule.

She did. Barely.

By five o’clock, her head throbbed and her feet ached. But she hadn’t quit. And from the way he glanced at her occasionally, as if checking if she’d crack, she knew she’d won a small battle.

Still, something was unsettling about the way he looked at her. Not like a boss watching an employee. Like something else. Something darker.

When the last of the office staff trickled out, Emily found herself alone with him on the top floor. The city glowed beyond the glass, night settling in. She gathered her things, desperate to escape before he gave her another impossible order.

“Emily.”

Her name rolled from his tongue like velvet and iron. She froze.

He stood by the window again, his silhouette framed by the lights. He didn’t look at her at first, only at the city. Then he turned, eyes locking onto hers with unnerving intensity.

“You lasted the first day.”

It didn’t sound like praise. It sounded like a warning.

“I told you I would,” she said softly.

He studied her in silence, then moved toward her slowly, each step measured. She forced herself not to retreat, though her pulse raced.

When he stopped a breath away, he lowered his voice. “If you’re going to work for me, there are rules.”

Her lips parted. “Rules?”

“Rules,” he repeated. “And they’re not just about business.”

Her heart lurched. “I—I don’t understand.”

“You will.” His gaze flicked to her mouth, then back to her eyes. “Starting tomorrow. Be here at eight. Don’t be late again.”

Emily’s breath caught. She wanted to ask what he meant, but something in his expression stopped her. He wasn’t just a man. He was a storm. And she was standing in the center of it.

As she finally slipped out of the office, his voice followed her, low and certain.

“Remember, Emily—if you work for me, you obey me. All of me.”

The elevator doors closed, sealing her inside with the echo of his words.

And for the first time, she wondered if she’d walked into a job… or into a trap.
