At 33, obsessive, hypersensitive Susannah Rabin lives with her mother, their cloistered world providing a barrier to the excruciating torment of human contact. But then Susannah's mother tells her that they are going to have a guest--Susannah's cousin, a young man from New York. Susannah is horrified.
