This was a very amazing and interesting book. It is very creepy and filled with haunting images but I would not say it is too scary. It was just the right amount of terrifying.
It annoyed me that the chapters were particularly long because I don't like stopping in the middle of a chapter but it was quite a fast read.
The characters are all very interesting and so are the powers they possess and the ancient photographs help depict the book in a way that i wouldn't have thought possible. The aspect of the photos immensely adds to the story helping you picture the photo in your mind as well as adding that extra bit of creepiness.
An amazing book!
