In Xanadu (Abridged Nonfiction‪)‬

Here is William Dalrymple's highly praised and greatly entertaining account of his 1986 trip made while a student at Cambridge, which retraced Marco Polo's route across land from Jerusalem to Xanadu. With him, he took a phial of Holy Oil, 600 pounds and Laura until Lahore, and Louisa from there to Xanadu.
