At age thirty, Kyle Boelte finds himself living in San Francisco, where the summer fog blows inland off the ocean and the landscape changes moment to moment. Amidst this ever-changing sea of fog, Boelte struggles to remember his brother Kris, who committed suicide in the family's Denver home when Boelte was just thirteen.In this impressive debut, Boelte sets up a dual narrative: one investigates San Francisco's climate to explain the science behind the omnipresent fog; another explores Boelte's memory as well as letters, notes, newspaper articles, and other artifacts that tell the story of his brother's short life and eventual suicide.Weaving a complex and engaging story from personal, historical and environmental threads, Boelte's search for meaning takes him to a range of unexpected places: from San Francisco Bay circa 1901, when fog was responsible for routinely sinking steamships, to a cavernous medical library where he studies the grim details of asphyxiation and death by hanging; from the redwood forests where scientists are now learning about fog's ability to sustain life, to a beat-up cardboard box containing memories of his long-dead brother.The Beautiful Unseen is as much a meditation on experiencing loss at an early age as it is a study of the impermanence of memory, the science of fog and the history of San Francisco.
