Author and pastor Audrey Wald grew up in the Deep South. When she wasn’t attending church services led by her evangelical preacher father, she was reveling in the classic Southern blues and rock of the 1940s and ’50s. Now living in the North Bay and leading the flock at St. Helena’s United Methodist Church, Wald is also the author of a recent memoir about her youth and its lasting impact, Hidden Biscuits: Tales of Deep South Revivals Told by Heart. This week, Wald speaks from the heart when she reads on Thursday, Jan. 14, at Napa’s Main Library, 580 Coombs St., Napa. 7pm. Free. 707.253.4235.
