Lives unlived: Light Perpetual, by Francis Spufford, reviewed

Francis Spufford was already admired as a non-fiction writer when he published his prize-winning first novel, On Golden Hill, in 2016. Set in 18th-century America, it was a tour de force of historical imagining, its prose skilfully suffused with the writerly tics of that era yet not overly so, leaving it pedantry-free and compulsively readable.

His new book, Light Perpetual, is also a historical novel, but with a difference. It follows the arc of the 20th century through the stories of five working-class Londoners, but its central conceit is a clever counterfactual. The opening scene sees all five, then young children, being killed in an air raid during the second world war. How, asks Spufford, might their lives have panned out had they lived?

Fiction that plays tricks with time has a pedigree, from Washington Irving’s Rip Van Winkle (1819) to Martin Amis’s Time’s Arrow (1991) to the many 20th-century children’s classics in which characters go back or forward in history.
