Jonah and Katherine thought the twenty-first century was supposed to be free from weird time flux phenomena. They were wrong. Sitting with their friends in class, suddenly they notice everyone has stopped moving, along with the clocks. Jonah and Katherine are immune since they have traveled in time before, and now they are about to do so again--this time back to 1903, when Albert Einstein's secret daughter Lieserl went missing. Jonah and Katherine will have to return Lieserl to her father before time can be fixed again.
