A particularly gifted author.
I appreciate that the way it was written using the voice of alternate characters allowed me to put it down when I read through heavy parts that required time to digest. (It also helps facilitate picking up where one leaves off.)
I had occasion many years ago, when visiting an art centre in Scottsdale AZ, to view a display of very old memory quilts somewhat similar to those described in the book. I value that experience even more now that I have read this book based on actual history.
