The book has many errors. I've started to read chapter one and it has many nouns/adjectives used wrongly and in almost every sentences "to" is used instead of the article "the". It doesn't sound too bad, but actually makes the reading very difficult. I suspect that this was a straightforward translation using a translation software. My advise is: buy another book, this one is not good.
This is a very handy country guide that you can complement with the cities top 10 guides. You have a great Turkey overview (I've used it for 3 different regions of Turkey!). Good tips for tourists as well!
