And here's some background about the author:
Magic is still a part of modern culture, according to Anton.Modern incantation bowls are already being manufactured.
"A quick Internet search will turn up a wide variety of amulets for sale, some quite similar to those of Rav Hisda's time," she said.
Does St. Christopher ring a bell? A pinch salt tossed over one's shoulder. A rabbit's foot? A four-leaf clover?
"Should my novel become popular, I wouldn't be surprised if Jewish artisans started manufacturing modern incantation bowls," Anton said.
Anton owns two incantation bowls — one in perfect condition, the other broken and repaired — which she bought on a trip to Israel to visit her son who was a student there at the time.
"I sometimes take the broken one to speaking engagements," Anton said.
She is not willing to risk the perfect one.
