'Til death do us part... or 'til demons do their worst.

Rosemary McGuire and Will Gordon's dream wedding is about to become a nightmare. Vista de los Robles may be a stunning historic mansion, but it comes with uninvited guests from Hell. Literally.

When a hideous demon crashes their romantic getaway, the couple must trade champagne toasts for holy water and vows for vanquishing spells. With their big day hanging in the balance, they call in the cavalry: demon-hunting power couple Michael Covenant and Audrey Barrett.

As the winter solstice approaches, the team races to uncover the mansion's dark secrets before "I do" becomes "I doom." Rosemary and Will must prove their love is stronger than any demonic force...or risk their happily ever after going up in unholy flames.
