Adalina has sold herself to the highest bidder, a fake wife contract for one year to get the Duke's territory back on track. It's so difficult to find a wife when you're possessed by a demon.
When the demon begins to covet the lovely Lina, an exorcism destroys the territory's hope of salvation. Lina must find a way to bring the demon back, even if that means using the Duke's brother to do so.
When she sold herself, it was to escape from a powerful demon of greed - and now she will need all of her knowledge to survive the gauntlet of Hell's Mountain to bring one home and save the people she's come to love.
