Fourteen-year-old Libby is hardly thrilled to find herself stuck on a highland holiday with her mum, her mum's new boyfriend and his young son, Cam. With her mum behaving like a teenager, and Cam sulking, a trip to the wildlife park is the only thing that animal-loving Libby is looking forward to! But when Libby and Cam get lost in the wilderness, the snow becomes a blizzard, and they stumble across an abandoned wildcat kitten, suddenly a fun day out turns into a life-or-death situation. Can Libby keep the kitten alive against the odds?
