Heath…has created an amazement of a novel which keeps singing in my heart with its feminist assertion and its feminine depths, its scientific muscle and its mythic invocations, its agony for the earth and its joy in life and love, its girlfriend intimations and its far flung vision, its wisdom that ‘dark matter…is the glue of the universe’ and its celebration of the ‘mysterious inter-relations of all things (which) people liked to call God.’
