In a style redolent of the the Kathasaritsagara, the author describes the culture and thought of medieval India while describing a pilgrimage from Lanka to Kasi (Benares). Along the way are hilarious retellings of Hamlet and Macbeth from an Indological perspective, disputations on the possibility of the existence of those 'liberated whilst alive' between Saiva and Vaisnava theologians, and so on and so forth.
In short, in addition to being very entertaining, this book can serve as an introduction to classical and medieval India. I recommend it highly and without reservation.
