This volume contains memoirs by Peake's widow and elder son, which I've reviewed separately:
Maeve's book, "A World Away", 4*, http://www.goodreads.com/review/show/487563887
Sebastian's book, "A Child of Bliss", 2*, http://www.goodreads.com/review/show/487566193
Published completely separately, I've also reviewed daughter Clare's book, "Under a Canvas Sky" which would actually fit far better with Maeve's. I rated it 4*, http://www.goodreads.com/review/show/258608942
