I enjoyed it, finding it very believable. I was a little distracted by the whole African-American theme, though I appriciated the comparison with the Underground Railroad. I guess I just had a hard time relating to the characters since I'm not African-American and the book focuses very much on that. Which is not to say that I was unsympathetic -- I definitely wasn't. It was just a little difficult for me to relate. Enjoyable, nonetheless. Would like to read more on this topic.
