Chapter 1

The plane's descent pressed Ava Williams gently back into her seat, a familiar pressure that signaled the end of one journey and the beginning of another. For three long months, her life had been a cycle of hotel rooms, construction sites, and video calls across time zones. She had just closed the biggest deal of her architectural career in Tokyo, a skyscraper project that would cement her name in the industry. But the satisfaction of that professional victory felt distant, a pale glow compared to the warm, bright anticipation of being home.

She rubbed the small, silver locket hanging around her neck. It was smooth and cool against her skin. Inside was a tiny, folded picture of her and Liam, taken on their first anniversary. His smile in the photo was wide and genuine, the kind that had made her fall in love with him five years ago. Tonight was his birthday, and her early return was a secret she had guarded for weeks, a surprise she couldn't wait to unveil.

In her carry-on was a small, beautifully wrapped box containing a vintage watch, something he' d pointed out in a magazine months ago. She pictured his face when he saw her, the initial shock dissolving into pure joy. She imagined him lifting her up, spinning her around in the foyer of their apartment, the home she had bought and meticulously designed two years before he even moved in. They would have cake, a special one she' d pre-ordered from his favorite bakery, and then she would give him his gift. The thought made a genuine smile spread across her face, chasing away the exhaustion from the fourteen-hour flight.

The taxi sped through the familiar city streets, the glittering skyline a welcome sight. She felt a knot of pure happiness tighten in her chest. This was it. The end of the distance, the end of the late-night calls where his voice sounded tired and far away. Soon, she would be wrapped in his arms, and everything would be right again.

She paid the driver, pulled her suitcase up the walkway, and rode the elevator to the penthouse floor, her heart thrumming with a happy rhythm. She stood before the solid oak door of her apartment, her sanctuary. She punched in the code, a sequence of numbers that was second nature to her: their anniversary.

A small red light blinked, and the lock emitted a sharp, negative beep.

Denied.

Ava frowned. She must have been more tired than she thought. Her fingers were clumsy from the long flight. She took a deep breath, centered herself, and carefully typed the code in again.

Beep. The same red light. The same rejection.

A flicker of confusion, then annoyance, sparked within her. This was her home. That code had been the key to her life for years. It was a number so deeply ingrained in their relationship that forgetting it would be like forgetting her own name. She thought, maybe Liam had changed it as a prank for her return, but that didn't feel right. He wasn't the pranking type, and he didn't even know she was coming home tonight.

A cold unease started to creep up her spine, pushing aside the warm anticipation. She tried another code, her own birthday.

Beep. Red light.

Then his birthday, the one she was here to celebrate.

Beep. Red light.

She stood there for a full minute, staring at the keypad as if it had personally betrayed her. The door remained shut, a silent, impassive barrier to her own life. The warm glow of her homecoming was gone, replaced by a growing sense of dread. The feeling was no longer just confusion; it was a cold, hard knot of anger. Someone had locked her out of her own home.
