Ghostly Deceptions by Jill James

The level-headed lawyer doesn’t believe in ghosts until she is possessed by one.
After witnessing her sister’s paranormal misadventures, Andrea Martin-Stovall persists in denying the spectral world exists. That doesn’t stop a ghost from taking over her body and mind.
Luke Tremaine is friend and business partner of the Ghost Releaser, but he remains a non-believer.
When the ghost destroys Andrea’s career, deceives her family and friends, and places her in danger, she and Luke will have to confront what is and isn’t real in the paranormal world. Will their new-found love be strong enough to survive the ghost and the deceptions?
