"I believe in expecting light. That's my job." A young interfaith chaplain is joined on her hospital rounds one night by an unusual companion: a rough-and-ready dog who may or may not be a ghost. As she tends to the souls of her patients—young and old, living last moments or navigating fundamentally altered lives—their stories provide unexpected healing for her own heartbreak. Balancing wonder and mystery with pragmatism and humor, Ellen Cooney (The Mountaintop School for Dogs and Other Second Chances) returns with a generous, intelligent novel that grants the most challenging moments of the human experience a shimmer of light and magical possibility.
