From New York Times bestselling author Kate Quinn comes a gorgeously written fantastical adventure which poses the question: Have you ever wished you could live inside a book? Welcome to the Astral Library, where books are not just objects, but doors to new worlds, new lives, and new futures. Alexandria “Alix” Watson has learned one lesson from her barren childhood in the foster-care system: unlike people, books will never let you down. Working three dead-end jobs to make ends meet and knowing college is a pipe dream, Alix takes nightly refuge in the high-vaulted reading room at the Boston Public Library, escaping into her favorite fantasy novels and dreaming of far-off lands. Until the day she stumbles through a hidden door and meets the Librarian: the ageless, acerbic guardian of a hidden library where the desperate and the lost escape to new lives...inside their favorite books. The Librarian takes a dazzled Alix under her wing, but before she can escape into the pages of her new life, a shadowy enemy emerges to threaten everyone the Astral Library has ever helped protect. Aided by a dashing costume-shop owner, Alix and the Librarian flee through the Regency drawing rooms of Jane Austen to the back alleys of Sherlock Holmes and the champagne-soaked parties of The Great Gatsby as danger draws inexorably closer. But who does their enemy really wish to destroy—Alix, the Librarian, or the Library itself?
