Violet and Iris sneak into the Eastwood Circle pool and Violet receives another message in French, which sends them to visit the Infinite Circle, where they learn the white circle Violet saw may have existed for hundreds of years, even before the disappearance of the Hopewell people in 400 AD.

As Violet continues her investigation at the library, she is threatened by a masked member of the Order of the Arranger who demands to know the location of the opening to other dimensions.
