Chapter 1

I smoothed the crimson tablecloth one last time, adjusting the crystal wine glasses until they caught the light from the candles just right. Our fifth anniversary deserved something special. Five years of building our life together, of supporting each other through residencies, fellowships, and finally attending positions at Mass General. Five years of love that had only grown deeper with time.

Or so I thought.

I stepped back to admire my handiwork. Our Beacon Hill townhouse looked magical, transformed by dozens of candles and delicate fairy lights strung across the dining room. The scent of Marcus's favorite osso buco filled the air, a recipe I'd spent days perfecting. I'd even picked up a bottle of the Barolo we'd shared on our first date.

"Ti amo più di ieri, meno di domani," I whispered, practicing the Italian phrase I'd memorized for our toast. I love you more than yesterday, less than tomorrow. My pronunciation was probably terrible, but Marcus would appreciate the effort.

I glanced at my watch. 7:30 PM. He'd promised to be home by 5:30. I tried his cell again, but it went straight to voicemail.

"This is Dr. Marcus Sterling. Leave a message."

I hung up without speaking. This wasn't the first time he'd been late, especially in the past few months. Surgeons kept unpredictable hours—I understood that better than anyone. Still, a text would have been nice.

I checked my appearance in the hallway mirror, smoothing down the emerald dress I'd worn on our first date. It was a little tighter now, but Marcus had always said green brought out the gold flecks in my eyes. My grandfather's voice echoed in my head: "Katydid, you look beautiful when you're excited about something."

Grandfather. The thought of him made me smile. I couldn't wait to tell Marcus about the breakthrough in Grandfather's research. After years of work, we were finally seeing promising results with the modified cardiac valve procedure. It would be the perfect anniversary gift—professional success to match our personal happiness.

The sound of keys in the door jolted me from my thoughts. I hurried to the entryway, excitement bubbling up inside me.

"Surprise!" I called as the door swung open.

Marcus stood there, briefcase in hand, looking startled and... something else. Distracted? Annoyed?

"Kate," he said, his eyes darting around the decorated space. "What's all this?"

My smile faltered. "Our anniversary? Five years today?"

A flash of recognition crossed his face, followed quickly by what looked like resignation. "Right. Of course." He set down his briefcase and loosened his tie. "I'm sorry I'm late. Surgery ran long, and then there was an emergency consult."

I swallowed my disappointment. "It's okay. The food's still warm."

He glanced at his watch. "Two hours late. I really am sorry."

But the apology felt hollow, automatic. He moved past me toward the stairs. "I need a quick shower."

"Marcus," I called after him, "I have news about Grandfather's research. The modified valve procedure—we're seeing incredible results in the trial."

He paused on the stairs, his back to me. "That's great, Kate."

No questions. No excitement. Just four words delivered with all the enthusiasm of someone acknowledging the weather forecast.

Twenty minutes later, we sat at the candlelit table, the food growing cold between us. Marcus picked at his osso buco, his mind clearly elsewhere.

"How was your day?" I asked, desperate to bridge the growing silence.

"Fine. Busy." He took a sip of wine. "This is good."

My phone buzzed on the table. I glanced down, ready to ignore it, when the image on the screen froze me in place.

It was a text from Lena Petrova, a colleague from cardiology. "Sorry, wrong recipient! Delete please!"

But it was the attached photo that turned my blood to ice. Marcus—my husband—standing in the hospital parking garage with his hand tenderly cupping the face of Ashley Chen, the new cardiothoracic resident. The gesture was achingly familiar—the same way he used to touch my face in our early days together. His expression was one I hadn't seen directed at me in months: complete adoration.

"Kate?" Marcus's voice seemed to come from far away. "What is it?"

I turned the phone toward him, my hand trembling. "Care to explain?"

The color drained from his face as he stared at the image. Then, something shifted in his eyes—not guilt or shame, but annoyance. As if I'd inconvenienced him by discovering his betrayal.

"It's not what you think," he said automatically, then stopped himself. His shoulders straightened as he met my gaze. "Actually, no. It is what you think. Ashley and I have been seeing each other."

The room tilted. "How long?"

"A few months."

"A few months," I repeated, my voice hollow. "On our anniversary."

He set down his fork with deliberate calm. "It's just a temporary derailment, Kate. These things happen in long marriages."

"Five years is a long marriage?"

"Don't make this more dramatic than it needs to be." His voice hardened. "And I'd appreciate if you didn't pressure Ashley about this. She's young, and this is difficult for her too."

The words hit me like physical blows. Difficult for her? I stared at my husband—this stranger across the table—and realized with sickening clarity that the man I'd married was gone. Perhaps he'd never existed at all.
