John Sedgwick's widely praised novels introduced readers to the rarified enclave of Brahmin Boston, in which privilege and elitism, handed down from one generation to the next, come at a price. He discovered for himself just how great that price can be when, while writing his second novel, he spiraled into a profound depression that threatened his life. This crisis provoked him to search for the source of his malaise. Did it begin with him, or did it begin before, possibly even long before, with previous generations whose genes he bore? If so, how had the "family illness," as he came to think of it, shaped their lives, and come to define his? To find the answers, he launched into a full-scale investigation of his family's history—one of the oldest, and fully documented in America. It was, at once, a very personal journey of self-discovery, and a broader retracing of his family's evolution, as he pored over the many extraordinary Sedgwicks who had gone before—from the protean early Speaker of the House Theodore Sedgwick through to Edie Sedgwick, Andy Warhol's muse and the 1960s "It Girl." Both a brimming family saga and a courageous narrative, the book paints a startlingly candid portrait of a man and an eminent American family.
