"On the same day Faye's brother comes home with a black eye, a package arrives from a relative they have never met. It's a slab of clay: some weird kind of bar mitzvah present? The strange gift turns out to be an invitation to learn a craft that has been in their family for centuries. And it's not pottery. Faye and Shiloh are driven to New York City by their grandfather for a spring break filled with magical instruction. But at night, they find themselves transported to a strange parallel world, where groups of innocent people are facing appalling hatred and violence. Are Faye and Shiloh destined to defend them? How is that possible for a brainy, unpopular eleven-year-old and her vulnerable older brother? It will take all the strength they can draw from their Jewish and Japanese heritage to not only crack the mystery of this alternate world but to find the power in them to confront the troubles of their present."--Provided by publisher.
