Darcys Utopia by Fay Weldon

A witty, satirical novel where the scandalous Eleanor Darcy, wife of a jailed economist, outlines her radical vision for a perfect society—free of money, with new names, easy sex, and communal child-rearing—to two journalists, Hugo and Valerie, who become captivated, abandoning their lives to pursue her ideas, sparking a cultural movement and exploring modern morality, gender, and idealism through sharp social commentary and dark magic undertones.
