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.
Stories have power.
In 1719, Elizabeth Goose 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.
Now, strange things are happening around the world. A tree-trimmer in Florida is blown off his elevated perch by a freak gust of wind, a woman in rural Pennsylvania is attacked by mutant rodents without any eyes, and a college professor in England finds 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 AWOL—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.
