The extraordinary debut of a classical pianist turned novelist, The Sage of Waterloo is a playful retelling of a key turning point in human history—and a slyly profound reflection on our place in the world. William, a rabbit living on the site of the Battle of Waterloo, attunes himself to the echoes and ghosts of the battle and comes to recognise how deeply what happened on 18 June 1815 continues to reverberate.
