Chapter 5
Fern woke up at five forty-two, which was eleven minutes earlier than yesterday and three minutes later than the day before. I knew these numbers the way I knew cytokine response curves — by heart, without thinking, data points that mapped a pattern I was always tracking.
I heard her first through the wall. Not crying — Fern didn’t cry when she woke up, not usually.
She made a sound that was part conversation and part announcement, like she was talking to someone I couldn’t see, reporting on the night’s events in a language only she understood.
I lay in bed for thirty seconds and listened.
The sound was cheerful. She wasn’t hungry yet.
She was just awake, and the world was there, and she had opinions about it.
I got up. The floor was cold. November had crept into the apartment the way November always did in Cambridge — through the windows, under the doors, settling into the floorboards like a tenant who didn’t pay rent.
I pulled on socks and a cardigan and crossed the three feet between my bed and the crib.
“Good morning, bug.”
She looked up at me with Liam’s dark eyes and smiled.
A real smile, the kind that used her whole face: mouth, eyes, the crinkled nose that was entirely mine.
She reached for me with both hands, fingers splayed, and I picked her up and held her against my chest and felt the specific weight of her — fourteen pounds, three ounces at her last checkup — settle into the crook of my arm like she’d been designed to fit there.
This was the best part of every day. The thirty seconds between picking her up and the rest of the morning starting.
Just the two of us in the half-dark bedroom, the nightlight still on, the city still waking up outside the window.
She grabbed a fistful of my hair and tugged, and I untangled her fingers and kissed them, and the day began.
The routine was a choreography I’d built from nothing.
Before Fern, my mornings had been loose — wake up when the alarm went off, coffee, shower, lab by eight if I felt like it, nine if I didn’t.
The Buchanan-marriage mornings had been even less structured: wake up in a house that had rooms I didn’t enter, drink the coffee the housekeeper left, wait for Liam to leave so I could feel like the space was mine for a few hours.
Fern’s mornings were precise. They had to be, because I was one person doing the work of two and the margin for error was approximately zero.
Five forty-five: diaper, clean onesie, the full-contact wrestling match that changing a seven-month-old involved — she’d recently discovered that rolling was an option and deployed it at every opportunity.
Five fifty-five: bottle. I sat in the rocking chair with her in my lap and watched her drink with the focused intensity she brought to everything.
Her eyes stayed on mine the whole time, and I talked to her while she ate — about the weather, about the experiment Rosa was running today, about the fact that the bananas she loved were getting brown and I’d need to stop at the market.
She listened with perfect attention, and I knew she understood none of it, and I told her things anyway because the sound of my voice was her world and I wanted it to be full.
Six twenty: my turn. I ate cereal standing at the kitchen counter while Fern sat in her high chair and dismantled a teething biscuit with methodical violence.
The kitchen was small enough that I could reach the counter, the fridge, and her high chair without taking a step.
I used to think that was cramped. Now I thought it was efficient.
Six forty-five: out the door. The stroller, the diaper bag, the insulated bag with the bottles for daycare, my laptop bag slung over one shoulder.
Cambridge in November was slate-gray and sharp.
The trees on our street had dropped everything and stood like skeletons against the sky, their branches dark and precise.
I loved this neighborhood. I loved the cracked sidewalks and the corner store that sold overpriced organic yogurt and the woman who ran the dry cleaner’s and always waved at Fern through the window.
None of it was beautiful. All of it was mine.
The daycare was six blocks from the apartment, in the basement of a converted Victorian that smelled like finger paint and Cheerios.
The director, a sturdy woman named Grace who had been watching children for thirty years and could calm a screaming infant by humming two bars of something unidentifiable, met me at the door.
“There she is.” Grace took Fern from my arms with the practiced ease of a woman who’d done it ten thousand times.
Fern went willingly — she liked Grace, liked the other babies, liked the chaos of a room full of small people doing incomprehensible things.
She didn’t look back when I left, which was exactly the sign of healthy attachment the books said it was and which still stung every single time.
I walked to the bike rack. My bike was a secondhand Raleigh that Kinsey had found at a graduate student sale and fixed up with the same intensity she brought to cell cultures.
It was blue and slightly too big for me and I loved it the way you love tools that keep your life running.
Seven minutes from daycare to the lab, cutting through the back streets where the traffic was light and the cold air hit my face like a slap and I felt, every morning, the raw freedom of being a body in motion with nowhere to be except the work.
The Cambridge Institute for Translational Medicine at seven-fifteen in the morning was mine in a way it wasn’t at any other time.
The lobby was empty. The corridors were lit but quiet.
My lab was dark until I flipped the switch and the overhead fluorescents buzzed to life and the familiar landscape of my work assembled itself — the assay bench, the modeling workstation, the coffee maker Rosa had brought from home because the department one produced something that tasted like regret.
I made coffee. Sat at my desk. Opened the co-authored paper I’d been writing with a researcher at Mass General — a review of biomarker prediction models for early autoimmune diagnosis that had been through four drafts and was almost ready for submission.
The writing was the part of the work I loved most and would never admit to anyone.
The lab work was rigorous and necessary and sometimes thrilling, but the writing — the careful construction of an argument from data, the sculpting of a paragraph until it said exactly what the evidence said and nothing more — that was where I felt most like myself.
Where I’d felt most like myself even during the marriage, on the rare nights when Liam was traveling and I’d sit at the desk in the study and write until two a.m. and remember what it felt like to have a mind that belonged to me.
Theo arrived at eight. Rosa at eight-fifteen.
By eight-thirty the lab was alive — machines humming, samples moving, the quiet, intent energy of people doing work they believed in.
I checked Theo’s latest batch of assay results, flagged two anomalies that needed re-running, and pulled up the patient data set we were preparing for the grant committee’s review.
The data was good. Better than good — it was the kind of data that made you sit up straighter, that made the correlations sharper with every new sample instead of fuzzier.
The IL-6 patterns in the pediatric cohort were tracking even more cleanly than the adult data, and if the trend held through the expanded sample, we’d have something publishable in six months and trial-ready in two years.
Metz had been right. The pediatric arm was the story.
I worked through the morning with the door open and the coffee maker cycling.
At ten, I walked to the institute café for a second cup and found Kinsey there, leaning against the counter with a mug in each hand and the look of someone who had been awake since four-thirty running a gel electrophoresis that she was either excited or furious about.
“Protein folding,” she said, handing me one of the mugs. It was mine — she’d brought it from the lab for exactly this purpose. “I think I’ve got a misfolding pattern that explains the degradation cascade. But I need to run it twice more before I trust it.”
“How many times did you run it already?”
“Three.”
“So you’ve run it three times, you see the pattern, and you need two more to trust it. That’s five replicates of a gel that takes ninety minutes each.”
“Seven and a half hours of gels. Plus analysis. Plus the write-up.” She grinned.
The grin was the one she wore when she was deep in something good — not the polished version she used at conferences but the raw, wired, slightly manic version that meant the science was working.
“I called in sick to my department meeting.”
“You don’t have a department meeting.”
“Exactly. Nobody will notice.”
We stood in the café and drank our coffee and talked about her misfolding pattern and my pediatric data and the paper I was finishing and the conference in March that we were both submitting abstracts to.
Normal talk. The kind of conversation that had been the backbone of my life since graduate school — two scientists in a hallway, holding coffee, arguing about methodology, building their understanding of the world one data point at a time.
