Five years after her first visit to the library, Kate is settling into her new life as a demonic librarian. It is a cozy life, but trouble is always looming on the horizon. Be it the extended family celebrating major birthdays or an occult study group forming at the local university, humans are always up to something. Kate must navigate humanity's chaos without revealing what she truly is, a task that has become increasingly difficult as her powers grow and curious humans stick their noses where they shouldn't be. She had been putting it off, but it is now time to decide if humans are worth the hassle or if she should fade into myth just as her librarian friends once did.

The Librarian is a direct sequel to The Library, which should be read first.
