Relax. Whatever that necklace was a present or she bought it to herself (i don’t know, but suits it’s from david) I’m sure she doesn’t wear it because of her book. The cover of We is the symbol of the triple goddess, it appears clearly in the side of the book (like the three moons symbol) it’s ancient, pagan and linked to women, so is the book. I don’t see that form in the necklace, just a chain!
