The mood of this book is suspenseful/dark. I say this because it feels like the mystery is never solved, you just feel that feeling of intense waiting for something to happen like "Oh come on, who is it, already?" And that is a good question. I will not spoil it, and will let whoever is reading this finish the book and solve it themselves.
