An extraordinary story of love and hope from the bestselling author of The Reluctant Fundamentalist

All over the world, doors are appearing.
They lead to other cities, other countries, other lives.

And in a city gripped by war, Nadia and Saeed are newly in love.
Hardly more than strangers, desperate to survive, they open a door and step through.

But the doors only go one way.
Once you leave, there is no going back.
