When Emily and Jamie hear that a new road will be built through Hilltop Wood, they rush to warn their friends, the Tomtes. Tomtes are very special creatures who guard the oldest woods. With the children's help, they immediately set about saving their home. When the workmen arrive, unexpected obstacles appear in their way: the rocks they need to move are much bigger than they remembered, their digging machines are flooded, a stream mysteriously changes direction over night. Maybe they won't be able to build this road after all... This is a charming picture book inspired by Elsa Beskow's classic stories of little folk.
