At least 4 stars. Great supernatural read for anyone who likes their narrator/main character to be believable and likeable. It's not scary- but I haven't read anything yet that is, to me.
The author uses actual vintage photographs, from my understanding, and weaves the story around them. I found myself completely engaged, maybe even a little sorry to see the end. Apparently, there will be at least one sequel and I'm looking forward to it/them.
