A fantastic light-hearted fantasy novel. The humour is strange - shades of Jack Vance - but very funny indeed. A particularly nice touch is a constant replacing of words... the people talk of hunting gazebo, shooting with their omnibuses, riding on a horse-drawn tumulus, and suchlike.
The story is a heroic fairy tale, and the Prince and his companions are quite aware of this and often decide what to do based on whether it would fit into the narrative or not. These moments are not too often, and are not overdone.
