After publishing "Warlock" (1981) and "Sundog" (1984), Harrison published "Dalva" (1988), one of his best-known novels. It is a complex tale, set in rural Nebraska, of a woman’s search for the son she had given up for adoption and for the boy’s father, who also happened to be her half-brother. Throughout the narrative, Dalva invokes the memory of her pioneer great-grandfather John Wesley Northridge, an Andersonville survivor during the Civil War and naturalist, whose diaries vividly tell of the destruction of the Plains Indian way of life. Many of these characters are featured also in "The Road Home" (1998), a complex work using five narrators, including Dalva, her 30-year-old son Nelse, and her grandfather John Wesley Northridge II. Harrison has been described as trying to get at "the soul history of where you live" in this sequel to "Dalva", in this case rural Nebraska in the latter half of the 20th century.
