One Light is a book about a Georgia mother and a daughter who must each take a turn at caregiving. In the first half of the book, the daughter tells of surviving near-fatal burns at age fourteen, and describes with stark straightforwardness the healing process, during which her mother serves as one of her primary caregivers.

In Part II, where both voices are alternately and jointly heard, the daughter moves reluctantly into the role of caregiver as her mother travels dementia’s haunting paths. Their shared love of singing and a stubborn tenacity serve as thematic threads.
