This book, the Life of Sister Mary of St. Peter, is a must for anyone interested in the Holy Face Devotion. It adds tremendously to The Golden Arrow. I cannot commend it highly enough! Read this book! No matter how slowly... you can store it on your desktop and just memorize the page where you left off. Using 125% magnification works well. You can highlight in yellow passages, and then save that version when done. Please Read this book. The devotion itself is peculiarly suited to our time. It builds upon the Devotion to the Sacred Heart. Our Lord explains how in the book. It is hard to puts quote from it on line... I had to basically copy paste and re-type and strange things occurred. I cannot attach the book in pdf as it is too big.
