A classic tale from China translated by by Arthur Waley. It is the story of a monkey king who creates mayhem in heaven and, as a result, is entombed under a mountain for 500 years. Then he agrees to escort a Buddhist monk on a journey to India to fetch scriptures, they are joined by various helpers on the way and have lots of adventures. I read this book to my daughter (who was then 11) and we both enjoyed it.
The final few chapters, in which they return to China, have a different atmosphere from the earlier ones: they are overtly religious and less playful; maybe they were added to the original at a later date?
