The story toggles between the past, as Flynn Carsen tries to find Aladdin’s Lamp before an ancient criminal organization known as the Forty Seals gets hold of it, and the future, when Eve Baird and a new group of Librarians—protectors of ancient artifacts like King Arthur’s sword Excalibur—stumble on a mystery in Las Vegas that seems to relate to the Lamp and the powerful djinn it can summon.

Stories can be powerful. In 1719, Elizabeth Goose of Boston Massachusetts published a collection of rhyming spells as a children's book, creating a spellbook of terrifying power. The Librarian of that age managed to dispose of all copies of the book except one, which remained in the possession of Elizabeth Goose and her family, temporarily averting any potential disaster. However, strange things are happening, A window washer in San Diego who was blown off his elevated perch by a freak gust of wind, but miraculously survived by landing on a canopy over the building entrance. A woman in rural Pennsylvania who was attacked by mutant rodents without any eyes. And, a college professor in England who somehow found herself trapped inside a prize pumpkin at a local farmer’s market. Baird and her team of Librarians suspect that the magic of Mother Goose is again loose in the world, and with Flynn Carson AWOL once again, it is up to Cassandra, Ezekiel, and Stone to track down the missing spellbook before the true power of the rhymes can be unleashed.

The Librarians and the Pot of Gold is an original novel based on the hit TNT television show The Librarians, by New York Times bestselling author Greg Cox. For millennia, the Librarians have secretly protected the world by keeping watch over dangerous magical relics. Cataloging and safeguarding everything from Excalibur to Pandora's Box, they stand between humanity and those who would use the relics for evil. There is truth to every story... Hundreds of years ago, the fate of the world rested upon the shoulders of a clever priest and a clever librarian. On the day the pair drove the remnants of the Serpent Brotherhood from Ireland's shore—that is, until the grave of an ancient sorceress is dug up and her remains removed. Now, Baird and her team of plucky Librarians find themselves on a collision course with their longtime foes as they race to find a leprechaun's lost gold to prevent the Brotherhood's dark design from coming to fruition.
