Prospero summons other fictionals in order to retrieve parts of his staff; the librarians find themselves pitted against Frankenstein's monster and Sherlock Holmes' nemesis Moriarty; Flynn and Baird have a disagreement.
Eve Baird is chosen by The Library to be a new Guardian as well as Ezekiel, Cassandra and Jacob who were asked to apply to the Library to become The Librarians, but weren't chosen in favour of Flynn Carsen.
While Flynn is searching for the Library (which is lost in time and space), the four become a new team of Librarians in order to solve impossible mysteries, recover powerful artifacts, and fight against supernatural threats, especially the forces of the Serpent Brotherhood, led by the mysterious immortal Dulaque.
