Surprise or ghost stories usually had many small gifts such as cards, bookmark, pamphlets, etc. These gifts could increase the collection value of the book. If you want to buy a book with suspense and ghost stories, I can recommend Ghost Blows Out the Light and Grave Robber's Chronicles. Both books had a lot of extras and the plot was very interesting. In addition, if you were interested in suspense novels, you could also read The Silence of the Lambs, Seven Deadly Sins, and so on.
