The sequel to S.E. Grove's New York Times best seller, The Glass Sentence. The events of The Glass Sentence transformed the world, as well as the life of 14-year-old Sophia Tims. Since then, she's continued searching for clues to her parents' disappearance, combing Boston's archives and libraries. Across the country, her friend Theo is searching, too, as an explorer's apprentice. When Sophia learns that her mother's diary - and the story of her parents' fate - is in a foreign archive, she makes a split-second decision and sets off on the journey with an almost complete stranger. As soon as Theo learns she is gone, he sets off on a voyage of his own. Written in alternating voices, studded with extracts from Sophia's mother's diary, and filled with all manner of wonders, including startlingly new kinds of maps, The Golden Specific is that wonderful thing - a second book that is even better than the first.
