Another twist ending that makes you wanna go, "OooOoOoOoOOOh" like a ghost! I had fun with this one but it was not as amazing as I remember - which is valid. I love the idea of a haunted house that is so big that 2 kids keep doing tour after tour to see it all and try and solve the legend of the headless ghost. The ending was superb and this is going to be one to re-read around Halloween for years to come!
