The astonishing story of the imcomparable Rex Libris, Head Librarian at Middleton Public Library. From ancient Egypt, where his beloved Hypatia was murdered, to the farthest reaches of the galaxy in search of overdue books, Rex upholds his vow to fight the forces of ignorance and darkness. Wearing his super thick bottle glasses and armed with an arsenal of high technology weapons, he strikes fear into recalcitrant borrowers, and can take on virtually any foe from zombies to renegade literary characters.

In this first collection of librarian adventures, rex must confront the powerful Space Warlord Vaglox and retrieve the overdue Principia Mathematica while his fellow librarians attempt to fend off a manifestation of blood-thirsty Vandals set on burning down the Middleton Library to the ground.
