Dylan was six when The End came, back in 2018; when the electricity went off for good, and the 'normal' 21st century world he knew disappeared. Now he's 14 and he and his mam have survived in their isolated hilltop house above the village of Nebo in north-west Wales, learning new skills, and returning to old ways of living. Despite their close understanding, the relationship between mother and son changes subtly as Dylan must take on adult responsibilities. And they each have their own secrets, which emerge as, in turn, they jot down their thoughts and memories in a found notebook - the Blue Book of Nebo. In this prize-winning novel, Manon Steffan Ros not only explores the human capacity to find new strengths when faced with the need to survive, but also questions the structures and norms of the contemporary world.
