On a quiet evening overlooking Puget Sound, a family gathers for dinner. Conversations move across rooms—subtle, ordinary, and familiar—yet something begins to take shape beneath them. Borrowed Certainty is a literary novel about how belief forms in real time: how attention gathers, how language circulates, and how reactions begin to feel like identity. Through a series of quiet, interconnected moments, the book reveals the often unnoticed forces that shape how we understand one another—and ourselves.
