Daniel, a college junior who somehow found his way in a History of the Occult class, is trying to keep his scholarship. With a degree he may not even want hanging in the balance, he decides to go all-out for this extra credit paper. But conducting a ritual from an old, forgotten textbook isn't one of his brightest ideas.

Not when it ends up being real.

After summoning a succubus and accidentally binding his soul to hers, Daniel is dragged to Hell where he waits for his demon to find a solution. He works in her shop, meets new friends, and builds a new life for himself while Feronia's allure grows by the day. One that asks him to submit.
