This intimate, poignant, and compelling memoir tells the story of a woman--a "reluctant examiner" of death--navigating grief while caring for her dying brother and aging parents, inviting the reader into a journey of hope, growth, and resilience. Deborah Cummins is "a stranger to death"--until, in 2007, she learns that her brother, Joe, is dying. In the months that follow, as Joe's health declines, Deborah confronts hidden truths in an attempt to make sense of her brother's death while he's still alive--truths that, in retrospect, where perhaps not so hidden after all. But before she's able to fully grasp her brother's worsening condition, Deborah is confronted with another family crisis: between complications following a recent surgery and her heartbreak over her son's condition, Deborah's mother's health is waning as well. After the death of her brother at only forty-five years old, her mother's death shortly follows, and Deborah must navigate grief compounded. Spanning the country from a small town in Maine to the sprawling metropolises of Chicago and Phoenix, Threshold skillfully and poignantly examines familial relationships between child, parent, and siblings, providing evocative portraits of each.
