A woman steps over the line into the unthinkable in this brilliant, powerful, and unforgettable new novel by the author of The lovely bones and Lucky. For years Helen Knightly has given her life to others: to her haunted mother, to her enigmatic father, to her husband and now grown children. When she finally crosses a terrible boundary, her life comes rushing in at her in a way she never could have imagined. Unfolding over the next twenty-four hours, this searing, fast-paced novel explores the complex ties between mothers and daughters, wives and lovers, the meaning of devotion, and the line between love and hate. It is a challenging, moving, gripping story, written with the fluidity and strength of voice that only Alice Sebold can bring to the page.
