In this sequel to the acclaimed middle-grade fantasy The Library of Ever, our heroine must save the magical library and make knowledge free for everyone.
After a wild adventure through space and time, Lenora returns to the magical Library—which holds every book ever known on its shelves. But she discovers the Library is under new management, and its incredible rooms and corridors have turned dark and sinister.
As Lenora tries to get to the bottom of the unsettling changes, she discovers a secret resistance movement trying to free knowledge from the shadows. Her new friends introduce her to an ancient lost city, hang-gliding, and mathematical beings larger than the universe itself. Together they must face the mysterious new Board that is leading the Library into darkness.
