The Architecture of Tranquillity

In the tea-brown light of a dying Victorian library, Layla Noor is racing time she does not have. Nine months into restoring the collection at Al-Hikmah, Manchester's last intact waqf estate, she has a roof that still leaks, a board of trustees running out of money, and a deadline that ends every December in the same place: not enough. What she does not have room for is a landscape architect. Zayd Mercer has come to survey the courtyard for a garden the trustees can't yet afford, and he has found something worth more than his fee: a salsabil, a nineteenth-century fountain built to slow water down rather than show it off, buried under sixty years of leaf mould.
He recognises it instantly. His father would have loved it. He is trying very hard not to think about that. Then a trustee with impeccable manners and a very good offer walks into the boardroom, and the shared wall between the library and the garden stops being the only thing at stake. Istibdal - the Islamic law that allows an endowment to be exchanged if the exchange serves it better - is either the estate's rescue or its unravelling, depending on who is arguing, and the vote is going to come down to people who have spent decades disagreeing about everything except the one thing that matters: this place is not supposed to be sold. Layla and Zayd are supposed to be colleagues working eighteen inches apart on either side of a listed brick wall.
What they become, over one difficult year of scaffolding, committee meetings, and a fountain neither of them can quite finish restoring, is something the waqf's own six-hundred-year-old deed put better than either of them manages to: not exchanged, not substituted - rebuilt. The Architecture of Tranquillity is a slow-burn, faith-forward love story about what it costs to preserve something worth keeping, and what two careful people find when they finally stop being careful with each other.
