My year of rest and relaxation

Young, thin, pretty, a recent Columbia graduate, an apartment on the Upper East Side of Manhattan paid for by her inheritance : our narrator has many of the advantages of life. But there is a vacuum at the heart of things, and it isn't just the loss of her parents. Or the way her Wall Street boyfriend treats her. Or her sadomasochistic relationship with her best friend. It's the year 2000 in the world's greatest city, aglitter with wealth and possibility.
What could be so terribly wrong ?
