This is my first Masterton book I believe, and it was certainly an interesting read.
It was so easy to read, I flew through the pages.
I'm always a fan of abandoned old hospitals and asylums, which are creepy, just by still being standing.
I'm very glad this was not an audio book, just reading about all the screaming was enough.
But there was good cause for all that screaming.
Some wince inducing moments to turn up the heat, and some characters that really came into their own.
I enjoyed this a lot.

DNF. The one non-white character cannot use proper English grammar despite being a well-respected army doctor in America. The only female character is described as fat to illuminate was a sad sack she is, yet the physical markers of other characters are never mentioned. Authors, please stop equating fat to unhappiness and low self esteem. Do better.
