When Julia Lambert, an art professor, settles into her idyllic Maine house for the summer, she plans to spend the time tending her fragile relationships with her father, a repressive neurosurgeon, and her gentle mother, who is descending into Alzheimer's. But a shattering revelation intrudes: Julia's son Jack has spiraled into heroin addiction. In an attempt to save him, Julia marshals help from her looseknit clan: elderly parents; remarried ex-husband; removed sister; and combative eldest son. Ultimately, heroin courses through the characters' lives with an impersonal and devastating energy, sweeping the family into a world in which deceit, crime, and fear are part of daily life. Roxana Robinson is the author of Sweetwater, which Booklist called a "hold-your-breath novel of loss and love." Billy Collins praised Robinson as "a master at moving from the art of description to the work of excavating the truths about ourselves." In Cost, Robinson tackles addiction and explores its effects on the bonds of family, dazzling us with her hallmark subtlety and precision in evoking the emotional interiors of her characters. The result is a work in which the reader's sense of discovery and compassion for every character remains unflagging to the end, even as the reader, like the characters, is caught up in Cost's breathtaking pace.
