The End?

The ending to Caucasia really bothered me. I felt it left so much unresolved. I mean she found her family, leaving one aspect resolved, however it left a lot open-ended. It doesn't explain what happens next. To me, it left the story unfinished. What becomes with her relationships with her family? What specifically was her mother involved in? Does she ever come out of hiding? What became of her relationship with her father? What becomes of Birdie's identity? What part of herself does she embrace? Or does she continue to possess whatever features work best for her in the situation? Does Cole ever see her mother again? Does Birdie? Overall I enjoyed the conflict and tension in the book, but I wish more answers would have been given at the end of the story.
