This Kindle Unlimited title caught my eye on a Facebook ad, and since I love a good ghost story, I downloaded and read it. It was fine; a little over the top (mainly the ghosts) and cheesy at times (dialogue), but what appealed to me the most was the setting of a haunted hotel, which was based on the Crescent Hotel in Eureka Springs, Arkansas. The author incorporated some of the sordid history as a cancer hospital with a fraudulent doctor who, as "Dr Pratt," is the devil himself in this novel (check out Ghost Adventures' exploration of the hauntings).
If you can get it for free and want a good diversion on a hot afternoon, give it a read, but if you want a truly scary haunted hotel story, you can't go wrong with The Shining by Stephen King.
