Haly is a Libyrarian, one of a group of people dedicated to preserving and protecting the knowledge passed down from the Ancients and stored in the endless maze of books known as the Libyrinth. But Haly has a secret: The books speak to her. When the threat of the rival Eradicants drives her from her home, Haly learns that things are not all she thinks they are. Taken prisoner by the Eradicants, who believe the written word to be evil, she sees the world through their eyes and comes to understand that they are not the book-burning monsters that she has known her entire life. The words of a young girl hiding in an attic - written hundreds of years before Haly's birth - will spark the interest of her captors and begin the change necessary to end the conflict between the Eradicants and Libyrarians. With the help of her loyal companion Nod, a creature of the Libyrinth, Haly must mend the rift between the two groups before their war for knowledge destroys them all. Haly's life - and the lives of everyone she knows will never be the same.
