I have to give thanks to all you goodreads reviewers of this book for not spoiling it for me. I had no idea, and the last 1/5 of the book raised my reading enjoyment from a 3 to a 4! Not everyone in the library book club liked the ending though. Some were confused and some just didn't like it. 
 I can see why this author is popular. The writing moves along and strategically throws in a juicy tidbit here and there, amping up the plot. 
 I don't know if I'll read more of her, because her other books seem to be about heavy issues.
