Fliss Morgan has a nightmare on the night before her school trip, to Whitby. Every night Ellie-May Sunderland is drawn to the landing outside the mysterious Room 13, which does not seem to exist during the day. Fliss and her friends attempt to unravel the mystery of the room, and determine the identity of its sinister inhabitant. Felicity "Fliss" Morgan: The main character. Fliss begins observing strange events in the hotel at night, and becomes determined to get to the bottom of what is going on. The book itself is about a group of tennagers who go on a schooltrip to Whitby and stay in a hotel. The main protagonist (Fliss I think) realises there is no Room 13 except at Midnight when a cupboard transforms into it. (Kind of reminds me of Toms Midnight Garden for some reason. Like I said I have a thing about the number 13). In the book there a ton of other mysterious and spooky(?) things apart from the room itself. Most of it points to the most infamous vampire in literature - as the setting suggests.
