The astonishing story of the incomparable Rex Libris, Head Librarian at Middleton Public Library, and his unending struggle against the forces of ignorance and darkness. With the aid of an ancient god who lives beneath the library branch, Rex travels to the farthest reaches of the galaxy in search of overdue books.
