Beverley Brewer is with her husband Jack at their cottage, unwinding after his chemo treatments for Stage 4 lung cancer. Her father has had a fall and needs attention. Driving to her father's home they find younger sister, Jacquelin, hanging in the den, the suicide note reading, "tell anyone I ever loved..."

So begins Bev's odyssey of looking back over a life spent as Big Sister to a sibling intent on self-harm. Alcohol, unsuitable lovers, false competency, bailouts, and suicide pacts are part of Jacquelin's life, with Bev always around to pick up the pieces and drill sense into someone who isn't listening.

Through the wreckage of Jacquelin's journey Bev comes to terms with her own, and deals with her husband's health crisis, her mother's death, and her father's looming mortality. Dance into the Light is a searing journey into loss, mental illness, addiction, and suicide. It is also a discovery of love, hope, and enlightenment gained by wading through the detritus of life.
