Hilda is besotted with Michael, because Michael has a gift. Through some mutation, his mind is able to perceive ‘lines of energy’ and ‘the vast ocean of movement’ – things beyond the limits of the five senses and perhaps even common understanding. But the gift, as so often in life, comes with a price. There are those who, in their resentment, come to covet the gift, threatening the blissful period of learning and freedom of thought that seemed so possible a future for Hilda and Michael. And then there are the expectations of society, whose demands for the idealised normal spell danger and disarray for the pair.
