Ah, so much to read, so little time!

I just finished a disappointing novel by Suzanne Berne called The Ghost at the Table. I was drawn to it because of the family situation which is similar to my own. Two sisters, the younger one, like mine, named Cynthia, who've grown up in the same household and harbor very disparate perceptions of their upbringing, in particular as it relates to their parents' relationship.
They live on opposite sides of the coast and the action revolves around a Thanksgiving reunion, hosted by Frances, the elder sister, who supposedly wants to reproduce a Norman Rockwell kind of idyll that is more her fantasy than reality.
This book was a quick read and actually well written but between the manipulative antics of Frances and the false memories of Cynthia, I just didn't like or relate to any of the characters well enough to care what happened to them in their childhood, let alone what's happening to them now!
