When Tariq comes back to bed, neither of them says anything. Laila reaches over and touches his face. Tariq's cheeks are wet.

50.

For Laila, life in Murree is one of comfort and tranquillity. The work is not cumbersome, and, on their days off, she and Tariq take the children to ride the chairlift to Patriata hill, or go to Pindi Point, where, on a clear day, you can see as far as Islamabad and downtown Rawalpindi. There, they spread a blanket on the grass and eat meatball sandwiches with cucumbers and drink cold ginger ale.

It is a good life, Laila tells herself, a life to be thankful for. It is, in fact, precisely the sort of life she used to dream for herself in her darkest days with Rasheed. Every day, Laila reminds herself of this.

Then one warm night in July 2002, she and Tariq are lying in bed talking in hushed voices about all the changes back home. There have been so many. The coalition forces have driven the Taliban out of every major city, pushed them across the border to Pakistan and to the mountains in the south and east of Afghanistan. ISAF, an international peacekeeping force, has been sent to Kabul. The country has an interim president now, Hamid Karzai.

Laila decides that now is the time to tell Tariq.

A year ago, she would have gladly given an arm to get out of Kabul. But in the last few months, she has found herself missing the city of her childhood. She misses the bustle of Shor Bazaar, the Gardens of Babur, the call of the water carriers lugging their goatskin bags. She misses the garment hagglers at Chicken Street and the melon hawkers in Karteh-Parwan.

But it isn't mere homesickness or nostalgia that has Laila thinking of Kabul so much these days. She has become plagued by restlessness. She hears of schools built in Kabul, roads repaved, women returning to work, and her life here, pleasant as it is, grateful as she is for it, seems… insufficient to her. Inconsequential. Worse yet, wasteful. Of late, she has started hearing Babi's voice in her head. You can be anything you want, Laila, he says. I know this about you. And I also know that when this war is over, Afghanistan is going to need you.

Laila hears Mammy's voice too. She remembers Mammy's response to Babi when he would suggest that they leave Afghanistan. I want to see my sons' dream come true. I want to be there when it happens, when Afghanistan is free, so the boys see it too. They'll see it through my eyes. There is a part of Laila now that wants to return to Kabul, for Mammy and Babi, for them to see it through her eyes.

And then, most compellingly for Laila, there is Mariam. Did Mariam die for this? Laila asks herself. Did she sacrifice herself so she, Laila, could be a maid in a foreign land? Maybe it wouldn't matter to Mariam what Laila did as long as she and the children were safe and happy. But it matters to Laila. Suddenly, it matters very much.

"I want to go back," she says.

Tariq sits up in bed and looks down at her.

Laila is struck again by how beautiful he is, the perfect curve of his forehead, the slender muscles of his arms, his brooding, intelligent eyes. A year has passed, and still there are times, at moments like this, when Laila cannot believe that they have found each other again, that he is really here, with her, that he is her husband.

"Back? To Kabul?" he asks.

"Only if you want it too."

"Are you unhappy here? You seem happy. The children too."

Laila sits up. Tariq shifts on the bed, makes room for her.

"I am happy," Laila says. "Of course I am. But… where do we go from here, Tariq? How long do we stay? This isn't home. Kabul is, and back there so much is happening, a lot of it good. I want to be a part of it all. I want to do something. I want to contribute. Do you understand?"

Tariq nods slowly. "This is what you want, then? You're sure?"

"I want it, yes, I'm sure. But it's more than that. I feel like I have to go back. Staying here, it doesn't feel right anymore."

Tariq looks at his hands, then back up at her.

"But only – only – if you want to go too."

Tariq smiles. The furrows from his brow clear, and for a brief moment he is the old Tariq again, the Tariq who did not get headaches, who had once said that in Siberia snot turned to ice before it hit the ground. It may be her imagination, but Laila believes there are more frequent sightings of this old Tariq these clays.

"Me?" he says. "I'll follow you to the end of the world, Laila."

She pulls him close and kisses his lips. She believes she has never loved him more than at this moment. "Thank you," she says, her forehead resting against his.

"Let's go home."

"But first, I want to go to Herat," she says.

"Herat?"

Laila explains.

THE CHILDREN NEED reassuring, each in their own way. Laila has to sit down with an agitated Aziza, who still has nightmares, who'd been startled to tears the week before when someone had shot rounds into the sky at a wedding nearby. Laila has to explain to Aziza that when they return to Kabul the Taliban won't be there, that there will not be any fighting, and that she will not be sent back to the orphanage. "We'll all live together. Your father, me, Zalmai. And you, Aziza. You'll never, ever, have to be apart from me again. I promise." She smiles at her daughter. "Until the day you want to, that is. When you fall in love with some young man and want to marry him."

On the day they leave Murree, Zalmai is inconsolable. He has wrapped his arms around Alyona's neck and will not let go.

"I can't pry him off of her, Mammy," says Aziza.

"Zalmai. We can't take a goat on the bus," Laila explains again.

It isn't until Tariq kneels down beside him, until he promises Zalmai that he will buy him a goat just like Alyona in Kabul, that Zalmai reluctantly lets go.

There are tearful farewells with Sayeed as well. For good luck, he holds a Koran by the doorway for Tariq, Laila, and the children to kiss three times, then holds it high so they can pass under it. He helps Tariq load the two suitcases into the trunk of his car. It is Sayeed who drives them to the station, who stands on the curb waving good-bye as the bus sputters and pulls away.

As she leans back and watches Sayeed receding in the rear window of the bus, Laila hears the voice of doubt whispering in her head. Are they being foolish, she wonders, leaving behind the safety of Murree? Going back to the land where her parents and brothers perished, where the smoke of bombs is only now settling?

And then, from the darkened spirals of her memory, rise two lines of poetry, Babi's farewell ode to Kabul:

One could not count the moons that shimmer on her roofs,

Or the thousand splendid suns that hide behind her walls.

Laila settles back in her seat, blinking the wetness from her eyes. Kabul is waiting. Needing. This journey home is the right thing to do.

But first there is one last farewell to be said.

THE WARS IN Afghanistan have ravaged the roads connecting Kabul, Herat, and Kandahar. The easiest way to Herat now is through Mashad, in Iran. Laila and her family are there only overnight. They spend the night at a hotel, and, the next morning, they board another bus.

Mashad is a crowded, bustling city. Laila watches as parks, mosques, and chelo kebab restaurants pass by. When the bus passes the shrine to Imam Reza, the eighth Shi'a imam, Laila cranes her neck to get a better view of its glistening tiles, the minarets, the magnificent golden dome, all of it immaculately and lovingly preserved. She thinks of the Buddhas in her own country. They are grains of dust now, blowing about the Bamiyan Valley in the wind.
