This weekend, AJC Decatur Book Festival attendees will be able to meet the doctor who beat Ebola.

“I don’t know how God works,” Kent Brantly said of how he survived the deadly virus, which he contracted while doing medical missionary work during the 2014 West African outbreak.

Brantly will appear at the AJC Decatur Book Festival on Saturday, where AJC Editor Kevin Riley will interview him and his wife, Amber, before a signing of the memoir they wrote together.

AJC readers can get an early look at that memoir, "Called for Life," online here, where it was excerpted in a recent installment of the Personal Journeys series.

Kent Brantly wrote in that excerpt of the moment he arrived at Emory for treatment, when he walked from the ambulance inside: "So many people had been praying for me, and I think to see me walking when they anticipated that I was on death's doorstep served as a live picture of answered prayer.

"I have been told countless times, 'When we saw you walk out of that ambulance, we just praised God.' "
