But all of these plans changed when Ronan was diagnosed at nine months old with Tay-Sachs disease, a rare and always-fatal degenerative disorder. Ronan was not expected to live beyond the age of three; he would be permanently stalled at a developmental level of six months. Rapp and her husband were forced to re-evaluate everything they thought they knew about raising a family. They would have to learn to live with their child in the moment; to find happiness in the midst of sorrow; to parent without a future.

The Still Point of the Turning World is the story of a mother's journey through grief and beyond it. Rapp's response to her son's diagnosis was a belief that she needed to 'make my world big' - to make sense of her family's situation through art, literature, philosophy, theology and myth. Drawing on a broad range of thinkers and writers, from C.S. Lewis to Sylvia Plath, Hegel to Mary Shelley's Frankenstein, Rapp learns what wisdom there is to be gained from parenting a terminally ill child. In luminous, exquisitely moving prose, she re-examines our most fundamental assumptions about what it means to be a good parent, to be a success, and to live a meaningful life.
