a mixed bag,
This review is from: Lonely Planet Central Asia (Paperback)
I found that the East Turkistan (Xinjiang) section of this book was much more helpful when I actually traveled there than the Cadogan "China: the Silk Routes" guide, which is much bigger and much lesse useful. For Uzbekistan, though, this book is useless compared to the Odyssey guide.
If you don't care to deeply know the history of the places you are visiting, then maybe this book is for you.
