In this swashbuckling middle grade debut, 12-year-old Dorrie Barnes falls through a passage in her local library into the headquarters of a secret society of heroic librarians. Your mission should you choose to accept it: support and promote the unsung heroes of literature, the defenders of the Dewey Decimal system, the freedom fighters of free speech—Ninja Librarians!

When Dorrie and her brother Marcus chase an unusually foul-tempered mongoose into the janitor's closet of their local library, they make an astonishing discovery: the headquarters of a secret society of ninja librarians.

Their mission: protect those whose words get them into trouble, anywhere in the world and at any time in history.

Petrarch's Library is an amazing, jumbled, time-traveling secret base that can dock anywhere there's trouble, like the Spanish Inquisition, or ancient Greece, or...Passaic, New Jersey. Dorrie would love nothing more than to join the society, fighting injustice with a real sword! But when a traitor surfaces, she and Marcus are prime suspects. Can they clear their names before the only passage back to the twenty-first century closes forever?
