Isaac Vainio has a problem: he is being hunted by vampires. Furthermore, they have already killed his friend and mentor, Ray Walker. Lucky for him, he has a fire-spider (that he pulled out of a book) named Smudge, who starts to ignite when danger approaches.
Isaac is a libriomancer- magical librarian of sorts. He is a cataloguer in a northern Michigan library, but he also catalogues the magical components of books for the Die Zwelf Portenaer, or the Porters as they’re known. The Porters, along with magical beings called automatons, help keep order in the magical universe.
Libriomancy was invented by Johannes Gutenberg himself five hundred years ago. The premise is that books become portals to the stories within, by way of the magical belief instilled by thousands of readers. Libriomancers can pull out any tool or weapon from books, as long as it’s smaller than the book’s physical dimensions. Gutenberg was the first libriomancer, and over the centuries, Die Zwelf Portenaer, or Porters as they are called, grew to include around five hundred members. (Gutenberg kept himself alive through the centuries by drinking from the Holy Grail that he pulled from the Bible.)
When Isaac is attacked in the library by a trio of vampires, he is rescued by Lena Greenwood, who is a dryad. The woman that Lena was in charge of protecting, was kidnapped and is being held hostage by vampires. Lena appeals to Isaac for help, and together, they start trying to piece together why vampires have declared war against the Porters.
Signs start to point to Gutenberg as the culprit, but Isaac and Lena can’t believe that Gutenberg would sacrifice everything that he worked so hard to create. Once they start digging deep enough, they figure out who the real troublemaker is. The question is, is it too late to stop him?
