Mrs Caliban by Rachel Ingalls

Dorothy is a grieving housewife in the Californian suburbs; her husband is unfaithful, but they are too unhappy to get a divorce. One day, she is doing chores when she hears strange voices on the radio announcing that a green-skinned sea monster has escaped from the Institute for Oceanographic Research – but little does she expect him to arrive in her kitchen. Muscular, vegetarian, sexually magnetic, Larry the frogman is a revelation – and their passionate affair takes them on a journey beyond their wildest dreams … Rachel Ingalls’s Mrs Caliban is a bittersweet fable, a subversive fairy tale, as magical today as it was four decades ago
