Set in southern Ontario during the 1980s, acclaimed poet Catherine Graham's debut novel is as layered as the open-pit mine for which it is named. Only child Caitlin Maharg lives with her parents beside a water-filled limestone quarry, but her idyllic upbringing collapses when she learns her mother is dying. After a series of family secrets emerges, she must confront the past and face her uncertain future. Lyrically charged, jewelled with images, and at times darkly comic, Graham's prose weaves a mysterious, hypnotic tale of loss, deception, and the courage to swim the depths of life alone.
