Having broken the Smedry Talents while saving the kingdom of Mokia from the Evil Librarian army, Alcatraz Smedry infiltrates the Highbrary as part of a desperate plan to save his comatose friend, Batille.

When the Librarian returns to his castle after lengthy travels, he finds that someone has stolen his collection of deadly books, and until he can get past a beast the thief left behind and track them down, the world is in great jeopardy.

One night, after awakening from a terrible dream, a young boy heads out on his bike. Soon he arrives at a mysterious cave, which he feels an urge to explore. Inside, a giant, deadly worm has trapped the Librarian! Now, the boy is in danger as well.

Alcatraz Smedry, his friend Bastille, a few pairs of glasses, and an unlimited supply of exploding teddy bears are pitted against an entire army of Evil Librarians and their giant librarian robots.

A young man gets a sliver from a strange book. That night, beneath the glow of a full moon, the man transforms into the Word Eater. The beast prowls the streets, searching for words to eat. If the Librarian doesn't stop it, every word and every thing on Earth could disappear.

Eleven-year-old Pearl Moran cannot imagine life without the historic but under-utilized branch of the New York Public Library where she was born (in the Memorial Room) and where her single mother works as the circulation librarian; the other librarians, the neighborhood people, the raccoons, and most of the 41,000 plus books all form the structure and essence of her life--but when someone cuts off the head of the library's statue of Edna St. Vincent...

Some books so evil that they must be imprisoned deep underground, but when the Librarian tries to dispose of one vile volume, he risks being buried alive in an eerie tower that holds a legendary secret.
