Kit doesn't understand why his family has been uprooted to a remote coastal village in the North. Why did they leave so suddenly, and why has his Dad not joined them? At Askfeld Farm Guesthouse, he meets an eclectic group of new neighbours and forms an unlikely friendship with Beth, who suffers from a chronic illness he does not understand. Kit learns that Beth, who cannot leave the guesthouse, is trying to draw a map from memory that shows all her favourite childhood haunts.
Kit makes it his quest to help her remember by visiting places for her and hopes to solve the problems of the other guests along the way. But becoming a hero like the ones in his favourite books is trickier than it seems. Can Kit work out that the person who really needs his help is much closer to home?
