After the death of a grandfather he never knew, Caleb Holdstock inherits a mysterious mansion. The place needs a lot of work if it's to be liveable, but the truly strange thing about it is what's in the basement. A doorway drawn in chalk. It seems harmless at first, until a midnight encounter with a silver-haired elf proves that this doorway is, in fact, the entrance to another world. With knowledge of a magical world beyond Earth, Caleb's life will never be the same again. And the best thing about it? He can travel back and forth freely.

Have you ever felt like there was something inside of you pushing your actions? A dormant beast, so to speak. I know it sounds crazy. But, that’s the best way I could describe how I’ve felt for a long time. I thought it was normal, some animal part of the human brain that lingered from evolution. But, this is the story of how I learned I wasn’t exactly human, and there was a world underneath our own where all the things that go bump in the night live. And, that my beast was very real indeed.

Awaking on the shores of a primitive world, David discovers a remote village populated almost entirely by women. Powerful witches have killed the men, destroying their tribal society. The women have little defense against the wild beasts and opportunistic goblin slavers who roam their forests. With a mysterious new power raging in his muscles, David becomes their guardian, provider, and leader. Beautiful women flock to him, believing he was sent by a sky god to protect them.

It was supposed to be a medical marvel. Instead, it triggered the apocalypse. Half of humanity mutated into mindless zombies. Half the survivors mutated into the inhumans: various new species of people with new appearances and abilities. Some grew scales, some grew fur, some could fly, some could survive only underwater. Decades passed, and from the ashes of the old world, a new patchwork civilization rose. Humans and inhumans lived in tentative peace, and the zombies turned out to be not much of a threat once a few generations of survivors had come and gone.

The devil paid me a visit and said I was going to one day rule his demonic kingdom. The catch: I have to attend the Infernal Academy, located in none other than Hell itself. Thankfully, I won’t be doing it alone. I’m going to surround myself with powerful demonesses (and maybe an angel or two as well).
