Joan Didion's electrifying first novel is a haunting portrait of a marriage whose wrong turns and betrayals are at once absolutely idiosyncratic and a razor-sharp commentary on the history of California. Everett McClellan and his wife, Lily, are the great-grandchildren of pioneers, and what happens to them is a tragic epilogue to the pioneer experience, a story of murder and betrayal that only Didion could tell with such nuance, sympathy, and suspense.
