Book excerpt: A blend of modern-day travel memoir and nineteenth-century history, “infused with the fresh air and spirit of the Northwest” (The New York Times Book Review). The author of the acclaimed This House of Sky and Mountain Time provides a magnificent evocation of the Pacific Northwest through his exploration of the unpublished diaries of James Gilchrist Swan, an early settler of the region who was drawn there from Boston in the 1850s. Winter Brothers fuses excerpts from these diaries with author Ivan Doig’s own journal entries, as he travels in Swan’s footsteps one winter along the once-wild coastline of Puget Sound and the Strait of Juan de Fuca. What emerges is a remarkable interaction of two minds, a dialogue across time that links the present with the reality of the American frontier. “Absorbing . . . A double portrait of striking clarity, yet with wonderfully subtle hues.” —San Francisco Chronicle
