first one is very vague. I think they were doing in series like goosebumps. The story is a girl and i think it was 2 boys or could be one were messing about somewhere on a cliff edge and one of them falls and dies and they leave them there and then they are tormented by the person that is dead and it turns out it was trick from the start. I also think i remember the girl being in a hospital bed when she finds out.
second book. Is a lad who works in a tannery as an apprentice and the master sends him to a place where there is a bear cub playing up and the boy manages to calm the animal and then another bloke hires the lad to work with the bear and he ends up having to run away with the bear as they want to kill it. It also tells the story from the bears point of view on every other chapter.
Any help would be greatly appreciated
