From the bestselling National Book Award finalist, a "masterful blend of history and memoir" San Francisco Chronicle featuring the author's three brothers as well as iconic brothers in history-John and Henry David Thoreau; Vincent and Theo van Gogh; John Harvey and Will Kellogg; Edwin and John Wilkes Booth; and Harpo, Chico, Groucho, Gummo, and Zeppo Marx. EDWIN BOOTH GREW UP TO BECOME THE GREATEST ACTOR ON THE nineteenth-century American stage while his younger brother John grew up to assassinate a president. Vincent van Gogh would never have survived without the financial and emotional support of his younger brother, Theo, in a claustrophobic relationship that both defined and confined them. Henry David Thoreau's life was shadowed by the early death of his older brother, John, who haunted and inspired his writing. Colt parallels his quest to understand how his own brothers shaped his life with an examination of the complex relationships between famous brothers in history. Illuminating and affecting, Colt's magnificent book is a history told through the lens of fraternal rivalry-and love.
