"Einstein's Dreams" by Alan Lightman is one of my favorite books!  It is several short stories about dreams Einstein may have had.  Each story captured my imagination. This is the first book that popped in my head. It really does stick out as my favorite.

I also enjoyed "The Dancing Wu Li Masters" by Gary Zukav.  It's a book about the connection between physics and spirituality.  It attempts to make a correlation between science and religion.  It's interesting.
