Chapter 12 · The Twelve-Hour Window

She woke at three.

This was not unusual for her — she had been waking at three for years — but tonight she did not, immediately, reach for her phone or for the kitchen. She lay in the dark. The ring, in her mind, was still filling. Most of what your liver does, it does quietly.

She drank from the glass of water on her nightstand.

She slept again.

She woke at five-forty. The light was just starting. She lay, again, in the dark, and felt — distinctly, embarrassingly — hungry. Not the dull, sweet hunger of a habit. The other kind. The clean, sharp, small hunger of a body asking, politely, for fuel. She had not, in years, woken hungry. She had woken thirsty, woken tired, woken dizzy. She had not woken hungry.

She picked up the phone.

The ring on the screen was almost full. Beneath it, the timer read 11:36. Beneath that, in soft letters: Twenty-four minutes. You're almost home.

She lay in the dark and watched the ring.

This, she would think later, was the moment. Not the diagnosis. Not the donut funeral. Not Beatriz's bench. This. Lying in her own bed at five-forty in the morning, watching a small, soft, animated ring complete its quiet circle, while inside her body — slowly, faithfully — the small, suffering organ behind her ribs took, at last, the rest it had been begging her for.

At six-oh-four, the ring closed.

The phone made a soft, almost private sound — not a chime, exactly, more like a single note from a wind instrument very far away. The screen said: You completed your window. Twelve hours. Beneath that: Drink a glass of water. Eat slowly. Tomorrow, we'll do this again.

Ellie put the phone on her chest. She put both her hands flat over it.

She did not cry, this time. She had cried enough, in the past week, to last a year. She did, however, allow herself a small, private smile — the smile of a person who has, for the first time in a very long time, finished something.

She got up. She drank a glass of water at the kitchen sink, slowly, the way the app had asked her to. She did not eat for another twenty minutes. When she did eat, it was two scrambled eggs, made with a teaspoon of olive oil, and half an avocado, and a slice of whole-wheat toast — no jam — and a cup of coffee with no sugar. She had not had coffee with no sugar in twelve years. The coffee was bitter, and complicated, and warm, and it tasted, she thought, oddly, like coffee.

Sophie came into the kitchen in her school uniform, dragging her backpack.

"Mom."

"Yeah."

"Why are you smiling."

"I finished my fast."

Sophie squinted at her. "How long did you fast?"

"Twelve hours."

"I fast every night. Don't I?"

"You do, peanut. Most people do. It's just — usually you eat dinner at seven-ish and breakfast at seven-ish, and that's twelve hours, and most people don't think about it. But for me, on purpose, doing it on purpose — that's a thing. That's a small thing. It's — it's a small thing today, and tomorrow it'll be a small thing, and a year from now I'll have done it three hundred times, and that's what doctors call a habit."

Sophie considered this. She accepted it, in the way Sophie accepted most things — as a piece of information about an adult world she would, eventually, have to live in.

"Okay," Sophie said. "I'm proud of you. Can we have eggs?"

"We can absolutely have eggs."

That night, Ellie wrote into the app:

Day Three. Fasting window completed: 12:04. Walked five blocks past Beatriz's bench. Slept seven hours. Ate eggs with Sophie. Mood: good.

She put the phone down. The ring, on the home screen, was waiting, empty, for the next night. The night, when it came, was easier than the first, by a small degree she did not think she would notice but did. The third night was easier than the second.

By the seventh night, when she lay down in her bed at ten o'clock, she did not think about food at all. She thought, instead, about the bench. She thought about the bowhead whale. She thought about Sophie's recital. She thought about a fox who, at the end of his book, was rewarded with a single, perfect plum.
