Something is wrong with the Galvins. An ideal family destroyed by madness

The Galvins seemed to embody the American dream: a father who was a war hero, a mother who was a model housewife, ten sons and two daughters, a large house in a picturesque valley. Each of the twelve children held great promise. Donald was an outstanding athlete, John and Brian were gifted musicians, and Richard was a capable mathematician. However, over time, those around them began to notice that something was wrong in the house on Hidden Valley Street…

The Galvin family kept a secret, but their skeletons in the closet became public knowledge and the main scientific mystery of the 20th century, which geneticists and psychiatrists struggled with for decades. Meanwhile, behind the scenes of years of research, a real tragedy unfolded: abuse, sexual violence, drugs, and even murder. Being a Galvin meant either going insane yourself or watching your loved ones do so.

Robert Kolker's brilliant investigation tells the incredible story of a family that gave hope for healing to millions of people.
