The Dunwich Horror

A single mother delivers a monstrous baby boy, somehow connected to a dark prophecy involving the Black Brotherhood, a book called the Necronomicon, and a demonic portal.
In Louisiana, in the wicked Whateley House, Lavina delivers two babies whose fate is written. Ten years later, three scholars of the occult discover that one page of the “Necronomicon,” the unspeakable book, is missing and the Black Brotherhood has summoned the ancient gate keeper to free legions of evil gods and monsters from the dimension of chaos.
