Sarah Holloway is a frustrated painter, sketching on the backs of shopping lists and sharing her studio with a washer and dryer. Abandoned by her mother, she has tried to hide her childhood wounds by healing others through art therapy. During her daughter's first two years, she has faked her way through motherhood with the help of women in her neighborhood playgroup. She hopes she has gotten the hang of it when she learns she is expecting another child. Then, a routine test reveals a mysterious mass in her unborn baby's abdomen. The sonogram awakens an old fear that her children have inherited her damage--and uncovers a secret that could end her marriage.
