This is my least favorite of her books I've read so far but it was still a good one to read.

Kitty pretends to be a nurse and gets hired at Portis House- a hospital for "mad" men who have returned from war to escape her abusive father. This is a haunted place where nightmares run rampant and the mystery of the previous owners and what happened to them is intriguing.

It had a very creepy, Gothic feel with the house being so isolated and the men inside having to deal with the after war trauma leads to a disturbing type of quality to this mystery.
