The book I’m searching for is out of print, last time I checked.  I believe the author is/was a woman who only wrote one book.

The book was set in New York City and was about a young woman moving to the city.  She met someone on her plane and they told her of an apartment that was available in a beautiful building.  The residents of that building had a supper club where they ate dinner together occasionally.  They started out eating exotic animals and gradually graduated to eating people.  Can you tell me the name of the book and the author?
