Two months after divorcing my wife because I believed our shattered marriage was destroying us both, I found her alone in a Chicago hospital.

Chapter 19

Day zero arrived on a Thursday and I have never seen anything like it.

They brought a small, frosted bag up from the blood bank in a styrofoam cooler with a biohazard sticker on it and a paper label that said HALE, S. — DONOR 4428. Inside the bag was four hundred milliliters of something the color of strawberry milk, which is the single strangest fact of my life: the entire future of the woman I love arrived in a lunchbox, and it looked like a smoothie.

The staff made a ceremony of it, which I did not expect and will never forget.

A nurse hung the bag on the pole beside Sophie’s bed. Dr. Raman stood at the foot of the bed. Two residents, a pharmacist, and Nurse Osei — who had come down from the fourth floor on her day off — stood in a ring. And Dr. Raman took a marker off the whiteboard and wrote, on the bare white wall above the bed, in big block letters:

DAY ZERO.

Sophie was awake. She was awake the whole time, which they had not expected. She had a mouth full of ulcers and a fever that had finally broken and a scalp with three days of fuzz on it, which is what happens when the chemo does not finish the job, and she lay there and watched the strawberry milk come down the tube into her chest and she did not stop watching it for an hour and ten minutes.

“Michael,” she said.

“He’s in the hall,” I said. “He’s not allowed in because of the infection risk. He’s been out there since six this morning.”

“Tell him something.”

“Anything.”

“Tell him it feels like water,” Sophie said. “Tell him it doesn’t hurt at all.”

I went out and told him. Michael Hale sat down on the floor of the corridor with his back against the wall and his mechanic’s hands over his face and did not get up for a long time.

The days after day zero are called the nadir and there is no better word for them.

Her counts did not move. They could not move. There were no cells in her to make counts. Every morning the nurse would draw blood and every morning I would write down four numbers that had not changed because there was nothing left inside my ex-wife to change.

And every morning, Dr. Raman would come in and say the same sentence.

“We wait.”

On day plus nine, the fever came back and did not leave.

On day plus eleven, her mouth was so bad they put her on continuous pain medication and she stopped talking to me, not out of anger — she simply could not, and there was nothing to be said about it, so I sat in the chair and read to her from the same novel her mother had been reading, starting over from chapter one, because Sophie had not heard the first eleven chapters and I wanted her to have them.

On day plus thirteen, at four in the morning, Nurse Osei drew blood and came back forty minutes later and said two words in the doorway, and her voice was not steady.

“Come look.”

I came and looked at the screen.

White count: 0.3.

I did not understand at first.

“That’s a count,” I said.

“That’s a count,” Osei said. “That’s her count. Colonel, those are her cells. That’s the graft.”

I sat down in the chair and put my head down on Sophie’s blanket and cried while she slept, and Osei put her hand on my shoulder and left us alone.
