With ‘both arms stretched out like a starfish, her long hair floating like seaweed at the sides of her body’, Kitty Finch swam naked into view in Deborah Levy’s Booker-shortlisted Swimming Home. Similarly, in Hot Milk, Sofia Papastergiadis loves to swim —as, indeed, does Levy herself. Only, whereas Kitty swims up and down the gravelike plot of a villa’s swimming pool, Sofia prefers the open expanse of the sea.
