Two children, a sister aged seven and a brother aged ten, embark upon a school outing to the Hill of the White Horse, deep in the heart of southern Oxfordshire.
Soon after their arrival, however, the mystery and unspoken magic of the hill and its surroundings begin to reach out to them, so much so that their lives will never be quite the same again.
It all happened on a single day, a mid-winter's day, not so very long ago.
Enter into a world which lies not far beyond what the eye actually sees and the mind believes. The Northlands is a place that our great ancestors might well have recognised, for it is a land where magic, guardian spirits, elves and giants are as real as you and I.
Under the Tree is the first of the ten Northland Tales.
