I have been searching for a book series I used to read in the 90s.
It was a young adult/teenage horror series and in every book it started with a sleepover, then one of the girls would tell the story - The individual stories I remember are
one about a headless horseman
one set in a ballroom
one set on a boat
and one set in a windmill.
Does anyone have any idea which books these could be? It's driving me mad!
