Chapter 1

Sarah touched her small, four-month bump.

Pure joy.

Her first baby.

She was an architect, used to designing solid, beautiful things.

This felt like her most important project.

Mark, her husband, sat beside her in the exam room at University Hospital.

He was an obstetrics resident here, ambitious, smart.

Today was a routine prenatal appointment.

Dr. Peterson smiled, her white coat crisp.

"Sarah, Mark, good news."

"The advanced screenings, NIPT, carrier screening, all look excellent."

"Baby is healthy, low-risk for common syndromes."

Sarah breathed out, a wave of relief washing over her.

Mark squeezed her hand, his smile wide, genuine.

"That's fantastic, Dr. Peterson."

This was their perfect start.

Dr. Peterson offered, "I can print a summary for you."

Mark waved a hand. "No need, I can access everything on the hospital system. Thanks, Dr. Peterson."

He was already turning to the terminal in the room, logging in with his resident credentials.

Sarah watched him, a small frown playing on her lips. He was always so efficient.

He clicked, typed, his eyes scanning the screen.

Then, his posture changed.

He leaned closer.

His smile vanished.

He scrolled down, to a section Sarah wouldn't understand, full of complex genetic markers.

"Mark? What is it?"

He didn't answer.

His face, usually open and cheerful, was slowly draining of color.

It turned a sickly, ashen gray.

Sarah' s heart began to thump.

He was staring at one specific line on the detailed genetic panel.

Rare recessive genetic disorders.

The report was stark, clinical.

Fetus: Homozygous.

A condition so rare, Sarah had never heard of it.

For this to happen, both biological parents had to be carriers.

Sarah felt a chill.

She remembered their pre-conception screening. Mark was definitely not a carrier for this. She' d seen that report herself.

But then, a faint, unsettling memory surfaced.

Hushed whispers at a family gathering years ago.

A rare gene, a quirk in the Miller family lineage.

Her family.

Mark knew this too. He knew her family history, or parts of it.

The implication hit Mark first, a brutal, silent explosion in his mind.

The baby wasn't his.

And the biological father… it had to be one of Sarah's close blood relatives.

His eyes, when they finally lifted from the screen, were cold, hard. Unrecognizable.

"This pregnancy," Mark said, his voice flat, devoid of any emotion. "It's non-viable."

Sarah stared. "What? Dr. Peterson just said-"

"She saw the summary," Mark cut her off. "Not the full detail. There's a severe genetic abnormality."

He was already reaching for his phone.

"We need to schedule a therapeutic abortion. Immediately."

He started dialing, his back to her.

The words hung in the air, sharp and cruel.

Therapeutic abortion. For their healthy baby.

A sudden, violent nausea churned in Sarah's stomach.

This couldn't be happening.

This perfect day, shattered.

The man she loved, erased. Replaced by this cold stranger.

The mystery of his transformation was a suffocating weight.
