A series called The Gentleman Mr Darcy declares its inheritance in four words. Julie Cooper writes inside the Austen variation tradition, that busy and surprisingly demanding corner of romance where a novelist borrows the most scrutinised characters in English fiction and then has to earn the loan.
It is harder than it looks. Readers of variations know the source intimately and will forgive a great deal except a Darcy who does not sound like Darcy. Only One Choice runs to nearly nine hours, which is novel length proper: room for consequence, for the slow work of a decision and everything it costs, rather than a quick reworking of a favourite scene.
The title alone tells you where the pressure sits. A choice narrowed to a single option is barely a choice at all, and that is usually where the interesting fiction begins.
