The Reawakening by Ann Evans
The peace of a remote Scottish valley is shattered when a team of ghosthunters arrive, intent on tracking down the vicious spirit of a sabre-toothed tiger, rumoured to have attacked two children. Daniel is sceptical - he only joined his dad on the trip for fun - but then he starts having strange paranormal experiences. It seems that the beast has returned and the hunters are to become the hunted.
