It was very interesting read! This is a historical fiction meets action, creepy and horror. The writing style is clean and easy to read. Also love how quick this book was to read couldn't put it down. It very very interesting. Overall it was a good book. I would change somethings as well as even though the book was a quick and easy read I found myself getting bored in the middle and beginning at times. Also it seem to lag in some areas and I found confusing at times but I think that is only because of the fact that this is a series. I came into this book not really knowing anything about this book, and author. But I would definitely like to read others of this series and author based off this book. The storyline and concept was very interesting and I like the attempt at this story. Mostly historical fiction are super sad and all about world War 2 but not this bad boy!
