In this heart-pumping sci-fi sequel to In the City of Time, two people have to work together to prevent the cataclysm that will soon break the laws of physics and render Earth uninhabitable. Now in possession of the most dangerous book ever scribed, Willa and Saudade settle into the nineteenth century and start planning how to avert the cataclysm that will soon break the laws of physics and render Earth uninhabitable. Faraz only wants his best friend, Leo, to have the time to come to terms with the death of his father--even if his father was a power-hungry villain who had to be stopped. But someone has stolen the editbook again, and now Faraz and his friends must track down Willa and challenge her for control of the editbook. Meanwhile, Leo's older brother Aris contemplates a path toward redemption after using the editbook to destroy the city of Napoli. Can he salvage his remaining relationships, after a lifetime of following their father? But as far as Willa and Saudade are concerned, all these people are suspects in a crime that hasn't happened yet.
