Spirit Guides and Angel Guardians by Richard Webster

Spirit Guides and Angel
Guardians: Contact Your Invisible Helpers by Richard Webster
They come to our aid when we least expect it, and they disappear as soon as
their work is done. We all regularly receive messages from our guardian
angels and spirit guides but usually fail to recognize them. This book aims
to help the reader to realize when this occurs. It contains numerous case
studies that show how angels have touched the lives of others.
