Set in the mythical small city of Sparta, New York, a young wife and mother named Zoe Kruller is found brutally murdered, the Sparta police target two primary suspects: her estranged husband Delray and her longtime lover Eddy Diehl. In turn, the Krullers's son Aaron and Eddy's daughter Krista become obsessed with one another, each believing the other's father is guilty. Told in halves in the very different voices of Krista and Aaron, Little Bird of Heaven is classic Joyce Carol Oates, in which the lyricism of intense sexual love is intertwined with the anguish of loss, and tenderness is barely distinguishable from cruelty.
