Where Angels Walk
This was the book that started it all for Joan Wester Anderson!  It is her first book in her series where she shares inspiring true experiences of ordinary people who believe that they have met and been helped by angels.  And it spent 55 weeks on The New York Times bestseller list.The book began as a personal pilgrimage for Joan when, on Christmas Even in 1983, her son and his roommate were rescued from certain death.  In the midst of subzero temperatures and gale-force winds, a man appeared and brought them to safety...and then disappeared.  Unseen by others, he left no tracks beside theirs in the snow.  Grateful and intrigued, she set out to explore an explanation for this incident only to discover that many others have had similar experiences.
