Libraries and librarians are the keepers of human knowledge. But one the Metropolitan Public Library houses more than you could ever imagine.
Flynn Carsen, a perpetual student with 22 academic degrees, is kicked out of college by his professor who tells Flynn that he lacks real life experience. When Flynn lands a job as the Librarian, keeper of top-secret treasures at the Met, he teams up with a gorgeous bodyguard to thwart thieves' plan to steal the artifacts.
Flynn Carsen, a year after his first mission as the Librarian, has been on many more death-defying missions to protect the world from evildoers. He meets Emily, a beautiful archaeologist who can match the much-educated Carsen degree for degree and together they endeavor to find King Solomon's mines.

An ancient organization hidden beneath the Metropolitan Public Library dedicates itself to protecting an unknowing world from the secret, magical reality hidden all around. The group solves impossible mysteries, fights supernatural threats and recovers powerful artifacts, including the Ark of the Covenant, the Spear of Destiny and Excalibur.
