I would really, strongly recommend Kinross's biography of Kemal Ataturk. He was the Julius Caesar and the George Washington of modern Turkey rolled into one. And the book acts as a really useful modern history of one of the most powerful countries in the middle east, as well.
I can only recommend English sources, I'm sure there are Turkish translations:
