The Sisterhood wraps a series of mind-raising questions in the gauzy trappings of a not-so-conventional romance.  What is an African American?  Who is an American?  Why the hyphen for some Americans, and not others?   Three educated, financially secure African American women approaching their middle years, fulfill a long-time dream with the treat of a vacation in Senegal only to be told by three local men they are not who they think they are.  Sisterhood Hyphen is that rare read stimulating both the mind and that good feeling when two hearts connect.
