Fiction by Harriet Lane.
The tag line on this novel was intriguing: "You don't remember her-- but she remembers you." And the beginning of the book was also very interesting: Nina, an artist with a teenage daughter, sees the pregnant Emma out pushing a stroller and immediately recognizes her as someone she knew long ago. Nina begins to watch Emma and slowly insert herself into Emma's life. But why?
The story was good through most of the novel but I felt like it began to fall apart a bit by the end. I felt like the plot was not really resolved properly and the ending was too abrupt. Still, most of the book was really good.
