The envelope from the state Department of Health arrived in August, addressed to:

Ryan Carter & Emily Carter

c/o Legal Representative Grace Holden (Retired).

Grace Holden, our attorney who had navigated the parentage petition and the Asteron settlements thirty years prior, had forwarded it with a sticky note:

Ryan—This is an informational notice under the new Voluntary Donor-Conception Registry Act. You are under zero legal obligation to respond. Call me if you have questions.

I read the letter at the kitchen table while Emily was drinking her afternoon chamomile tea.

The state legislature had passed a statute creating a centralized, voluntary contact registry for historical assisted-reproduction cases between 1985 and 2010. Because Harbor Ridge had operated under a state license during that period and had been subject to regulatory sanctions regarding consent documentation, all former patients whose records contained verified inventory reconciliation entries were being notified of the registry's existence.

The letter stated:

A registered party whose genetic or gestational profile matches archive cluster HR-1999-RC has requested reciprocal non-identifying contact.

My heart slammed against my ribs like a trapped bird.

Cluster HR-1999-RC.

That was our account code.

I picked up the phone and called Sophie immediately. "Are you home?"

"At the clinic. What’s wrong?"

"Come over after work. Bring Daniel."

When Sophie arrived, Daniel took Emily out to the backyard to look at the tomato plants, leaving Sophie and me alone at the kitchen table. I slid the letter across the wood.

Sophie read it silently. She didn't gasp. She didn't cry. Thirty-odd years of unexpected administrative documents had inoculated her against sudden shock.

"A registered party," she said slowly. "What does that mean?"

"It means someone logged into the state registry using an identifier derived from our old Harbor Ridge records," I said.

"Could it be... another embryo?"

The question hung in the room, heavy and suffocating.

"The independent audit thirty years ago confirmed that only one unauthorized transfer occurred from our cohort," I said, repeating the facts like a litany. "Two embryos failed after thaw. One became Lily. Three remained in cryostorage until Emily and I released them to university developmental research. That accounted for all seven viable blastocysts."

"Unless the audit missed something," Sophie said.

Her voice was entirely devoid of panic. That frightened me more than tears.

"Do you want me to call Grace?" I asked.

Sophie looked at the official state seal on the top of the stationary. "The letter says 'genetic or gestational profile'. It doesn't say a child. It could be someone from Caroline Mercer’s extended family. Or someone related to the Morris family—the couple whose consent form had our code mistakenly attached during the database migration."

"Robert and Elaine Morris," I remembered. "The clerical cross-reference."

"Or it could be someone who worked at the lab," Sophie said. "Paula Kent. Or one of the storage techs."

"Do you want to know?"

Sophie sat back in her chair. She looked around our small kitchen. She looked through the window at Daniel patiently guiding Emily’s hand to touch the fuzzy leaves of a late-summer tomato vine.

"When I was nine, Lily asked how many sisters were in the freezer," Sophie said quietly. "And for years, I treated those three stored embryos as if they were ghosts waiting for me to rescue them. Then we gave them to science. And I realized that DNA isn't an obligation to form a relationship."

"The registry is voluntary," I said.

"If I sign this paper," Sophie said, touching the form, "I reopen the warehouse. More investigators. More genetic counselors asking me how I feel about my identity. More people looking at me like I’m a headline instead of a mother who has to help her daughter pack for her second year of college."

"You don't have to sign," I told her.

"What if it’s someone who needs medical history?" she asked. "A clotting trait? A genetic marker?"

"We submitted our full, anonymized medical profiles to the state health repository as part of the Asteron consent decree thirty years ago," I said. "Any person with a legitimate medical claim can access our genetic sequencing through a physician without ever knowing our names."

Sophie picked up the letter. She folded it along its original crease, then folded it again into a small, tight square.

"Then I don't need to know," she said.

"Are you sure?"

She looked at me with Caroline Mercer’s brown eyes and Emily Carter’s jawline. "Dad, my life is full. I have a husband. I have a daughter. I have a sister who designs hospitals. I have a mother who is forgetting my name, and a father who keeps receipts in a crawlspace. I don't have room for another ghost."

She dropped the folded square into the recycling bin beside the refrigerator.

It landed with a soft, hollow thump against an empty cereal box. We didn't speak of it again.
