Richmond's sophomore novel (after The Girl in the Fall-Away Dress) is a bleak melodrama about a young woman's prolonged grief over the death of her best friend and former lover. Twelve years have passed since college student Amanda Ruth was brutally murdered, and her sidekick Jenny has yet to recover. Jenny and her estranged husband, Dave, take a cruise on the Yangtze to scatter Amanda Ruth's ashes in the homeland of Amanda's Chinese father. Although Jenny wants to save her marriage, she rather coolly trashes it by becoming intimate with Graham, a cruise passenger who, despite suffering the final throes of Lou Gehrig's disease, manages to show Jenny around and teach her about the environmental perils facing China. Jenny's relationship with Graham takes a dark—and implausible—turn when she learns of his wish to commit suicide. Through it all, she continually relives her friendship and adolescent romance with Amanda Ruth. Her obsession with the young woman leads her to engage in troubling behavior, propelling the plot into a moral wasteland where the environment becomes the object of desire and human life is casually snuffed out. Richmond's prose tends to run purple, especially during Jenny's brooding monologues, which dominate the book ("I gaze into the dark depths of the river, looking for some reflection of the woman I am now.... But the river is opaque, and my vision is blurred"). Though Richmond poses provocative questions about grief and desire, the shallow characters and sensational plot twists don't allow her to explore them in much depth. (Feb.)
