“Antique looking books seem perfectly harmless until someone walks by, then the middle book slides out toward the victim as if it will fall from the shelf. Books also emit spooky sounds for a totally haunted effect.”
They are calling them Possessed Books and they sell for $25.
There is also a little video clip of them in action at the above link.
For an added fee they should let you pick the titles for the spine labels.
Any ideas?
