Early one September, Nick Hayes brought his houseboat up the Thames into rural Oxfordshire, mooring opposite a strange tree that towered over the surrounding meadowland. The tree, he would discover, was a hybrid of the eastern cottonwood, brought back from colonial Canada. The land was the Hardwick estate, whose apparently timeless tranquillity - like so much of the English countryside - masks a darker history. Yet Hardwick also tells another, quite different story.

Over the following months, Hayes learns that its rolling hills and fertile valleys are on the front lines of a battle between ownership and belonging. Through a golden autumn, and the frosts and floods of winter and early spring, Hayes explores an estate that, acknowledging the colonial origins of its wealth, has become a haven for those who are both unable and unwilling to be part of a countryside geared towards profit at any cost. Living and working among this extraordinary community of farmers and craftspeople, Hayes contemplates what we have lost in England, as our sense of kinship with the land, and the deep knowledge that arose from it, was destroyed.

Yet, Hayes suggests, if we can learn from the cultures we have exploited, and from the tentative roots being put down in this radical Oxfordshire estate, perhaps we can start to unpick - and even re-enchant - our relationship with the land. The Medicine Tree is a singular act of storytelling and recovery: of giants, gods, witches, trees, horror and hope, of entanglement, reparation and solidarity.
