For thousands of years, the Librarians have secretly protected the world from dangerous magical relics, everything from Pandora's Box to King Arthur's sword. Ten years ago, Flynn Carson was the only living Librarian. When the ancient criminal organization known as the Forty steals the oldest known copy of The Arabian Nights by Scheherazade, Flynn is called in to investigate. Fearing that the Forty is after Aladdin's fabled Lamp, Flynn must race to find it before the Lamp's powerful and malevolent djinn is unleashed upon the world. Today, a new team of inexperienced Librarians, along with Eve Baird, their tough-as-nails Guardian, is investigating an uncanny mystery in Las Vegas when the quest for the Lamp begins anew . . . and the fate of the world hangs in the balance.
