GANGED-UP BY GHOSTS by Imogen Forester is not just erotica with a supernatural twist, but also has a bit of background. The main character is a paranormal investigator who conducts a live stream. She travels abroad to investigate a place where many soldiers died. She's missing her boyfriend, the spirits are missing their girlfriends and wives.
I expected something along the lines of The Entity, but this is more like a reverse harem situation with zero violence. Just a psychic helping some ghosts release their spirits in more than one way.
If the author included a little more info about her live stream job, as well as the specific history of the location, this would be more of a paranormal thriller than a spank-piece. I would also suggest changing the title to something like, "Seduced by Spirits" to be more inviting.
As always,

*UPDATE* Looks like the author changed the title and cover on Amazon, so this review has been edited to reflect that as well. The cover on the right is the original.
