Ann and Wade have carved out a life for themselves from a rugged landscape in northern Idaho, where they are bound together by more than love. With her husband's memory fading, Ann attempts to piece together the truth of what happened to Wade's first wife, Jenny, and to their daughters. In a story written in exquisite prose and told from multiple perspectives--including Ann, Wade, and Jenny, now in prison--we gradually learn of the mysterious and shocking act that fractured Wade and Jenny's lives, of the love and compassion that brought Ann and Wade together, and of the memories that reverberate through the lives of every character in Idaho. In a wild emotional and physical landscape, Wade's past becomes the center of Ann's imagination, as Ann becomes determined to understand the family she never knew--and to take responsibility for them, reassembling their lives, and her own.
