A Thousand Acres by Jane Smiley
Larry Cook is an aging farmer who decides to incorporate his farm, handing complete and joint ownership to his three daughters, Ginny, Rose, and Caroline. When the youngest daughter objects, she is removed from the agreement. This sets off a chain of events that brings dark truths to light and explodes long-suppressed emotions, as the story eventually reveals the long-term sexual abuse of the two eldest daughters that was committed by their father. The plot also focuses on Ginny's troubled marriage, her difficulties in bearing a child and her relationship with her family.
