For her second novel, Madeline Miller returns to the fertile world of Greek mythology, and to another figure often overshadowed by a swaggering hero. This time her protagonist is Circe, sorceress and nymph, ruler of one of the many islands where Odysseus manages to get lost en route from Troy to Ithaca. Artists have always loved Circe: John William Waterhouse, in particular, seems to have been obsessed with this exotic enchantress. And yet Miller invites us to look beyond the magic, the sensuality and the unfortunate habit of turning people into pigs. As she did in The Song of Achilles, she gathers strands of myth from various sources and reveals little-known aspects to a familiar figure. Like Penelope, Miller is a master weaver; and yet there’s something at the heart of the book that doesn’t quite work.
