Mistletoe and Spirits by Amy Boyles

Blissful is locked in a house full of spirits two days before Christmas? Will she escape in time to enjoy Christmas with Roan?

Blissful Breneaux is expecting a quiet, uneventful Christmas with her fiancé Roan, but all that changes when a ghost from her past needs her help locating someone—Blissful’s father, Vince Breneaux, who happens to be dead. With the help of a local medium and her annual Christmas seance, Blissful is ready to tackle the job.
But things go haywire when the medium winds up with a knife in her chest. Things get worse when Blissful finds herself locked in the house with the seance guests, one of whom is a murderer. Unable to escape until morning, Blissful has one night to find the killer and contact her father. Can she survive long enough to do both, or will Blissful become the next victim of the Christmas murderer?
