Autumn was never supposed to know that the incubus who visited her dreams every night was real. But when she wakes up in the middle of the night to find the demon Irdu in her bed, she surprises them both by inviting him to stay. What starts as an arrangement of convenience quickly turns into something much deeper. But a relationship between them can never be. An incubus is bound in service to the Underworld, and the only way to free Irdu is if Autumn pays with her soul. The deeper she falls in love with him, the closer she comes to damnation. With the Underworld in turmoil and the fate of their love on the line, Autumn and Irdu must risk everything to be together.
