At the heart of Cast The First Stone is the autobiographical account of transformation and redemption as the author unexpectedly was converted to Christianity. Preconceptions and social restrictions are challenged and willingly altered as she recognises their futilities in the light of understanding and grace. Through the struggles in a loveless marriage there are highlights and holidays, laughter and learning, amazing breakthroughs and tragedies. The reader will learn that God does permit divorce under certain circumstances but that far from ending in failure, this story will bring hope to those facing similar circumstances.
