Book excerpt: For fans of The Golden Compass, this is book two in the Mapmakers Trilogy and follow-up to S.E. Grove's stunning debut, The Glass Sentence It is the summer of 1892, one year since Sophia Tims and her friend Theo embarked upon the dangerous adventure that rewrote the map of the world. Since their return home to Boston, she has continued searching for clues to her parents’ disappearance, combing archives and libraries, grasping at even the most slender leads. Theo has apprenticed himself to an explorer in order to follow those leads across the country—but one after another proves to be a dead end. Then Sophia discovers that a crucial piece of the puzzle exists in a foreign Age. At the same time, Theo discovers that his old life outside the law threatens to destroy the new one he has built with Sophia and her uncle Shadrack. What he and Sophia do not know is that their separate discoveries are intertwined, and that one remarkable person is part of both. There is a city that holds all of the answers—but it cannot be found on any map. Surrounded by plague, it can only be reached by a journey through darkness and chaos, which is at the same time the plague’s cure: The Golden Specific. "This delicious blend of magic, history, and science will continue to delight fans of intricate world-building and rich storytelling."—School Library Journal "Readers who have already read the first installment will gladly savor another journey with Sophia and marvel at the worlds they enter. Brilliantly imagined and full of wonder."—Kirkus Reviews
