Loose connections

Jake's dad is away and his pregnant mum is in hospital, so his granny is looking after Jake - or so they think. But Gran has changed. She tends to be dazed or confused, fills Jake's sandwiches with strange combinations of food, leaves the cooker on, and wanders down the road in her nightie in the middle of the night. Jake doesn't want to worry his parents, so he tries to look after Gran himself. But help comes from a mysterious quarter, in the form of a strange, ghostly girl called Verity.
