On Saturday, October 26, at 12:00 p.m. the Signal Mountain Library will host a presentation by local writer Sue Carol Elvin, author of The Memory Guardians: The House on Stone Street. Elvin will read excerpts from her book. She describes the story as follows: “Two spirits, Boogery Mungo and Umbriago (Boo and Iago), are assigned to the attic of a 120-year-old house to capture and absorb memories over time from the day the house was built. These Memory Guardians share wonderful stories of family love and challenging times on Stone Street.”
