A Special Relationship

I read A Special Relationship by Douglas Kennedy which tells the story of Sally and Tony who meet as foreign correspondents, marry, settle in London and have a baby.  Then Sally suffers serious post natal depression.  The story is told in the first person by Sally, so the reader gets to know her well.  She has to fight for her rights in an "alien" legal system. (Sally is American).  I found the book was too long (500 pages) and I became tired of reading about Sally's problems.  I can't say too much as that would be a "spoiler".  I question the title as the "special relationship" was obscure (unless between Sally and her son??).  31/2/5
