A new SUPERNATURAL book is coming and it’s one you’ll definitely want to add to your collection, especially if you’re a hunter!

Yes, folks! After twelve seasons, someone finally felt there were enough monsters, ghosts, demons, and other evil creatures in the show to create their own Supernatural bestiary.

If you’re unfamiliar with the term, bestiary, it’s basically a book, or a guide of monsters, creatures, and such. In the world of Supernatural, the Men of Letters Bestiary is also sort of a journal as it’s told in the voices of Sam and Dean Winchester, our favorite hunter brothers.

Check out the cover and some of the illustrations and pages inside that feature a few familiar faces from the show.

Supernatural: The Men of Letters Bestiary hits stores September 12, but you can pre-order it here.

The thirteenth season of Supernatural premieres Thursday, October 12th at 8pm on the CW, which is actually a highlight video from San Diego Comic-Con 2017.
