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. 

It addresses female sexual freedom and agency. It asks the reader to examine what it means to be human ... Genius.
