How long would it take to walk from Shanghai to the edges of Tibet? Long-time China resident Graham Earnshaw is in the process of finding out. His westward trek is described in his new book, The Great Walk of China, out at the end of this month.

Through his conversations with the people he meets along the way, Earnshaw paints a portrait of a nation struggling to come to terms with its newfound identity and its place in the world. Our wandering guide never backs away from sensitive and sometimes uncomfortable topics, and captures the essential kindness and generosity of the Chinese people with brilliant clarity.

We have three copies to give away to readers who can answer this question: Which city beginning with W is the capital of Hubei province?
