As our lifespans continue to grow longer, millions of people every year spend time caring for the elderly and dying—some as professionals, some as volunteers, and some through their loving but demanding care for parents, spouses, or other family members or friends.

In her book In the Mystery’s Shadow, Susan Swetnam draws on her experience serving thousands of ill and dying clients, often in hospice programs, as a certified massage therapist—and also on her experience of caring for her own husband, who died young of cancer. She explains how this sometimes difficult work offers not just the fulfillment of giving comfort to people who need it, but also moments of breathtaking wonder, moments that hint at the untold complexity of being human and affirm our sacred connections with each other. She writes of the hard lessons caregivers learn about themselves, while at the same time knowing the strange and humbling sense of being used in the service of God’s love. Insightfully connecting end-of-life care with the liturgical year, Swetnam invites those who care for the sick and dying, whether professional or volunteer, to stay awake to the sacred implications of their labors.
