If you want the past to come alive read "Birds without Wings" a work of fiction but set in Kayakoy at the time of partition, its also a good account of the battle at Galipoli, and the hardships that the ordinary Turkish soldier suffered. Also there is a good account of the life and times of Mustafa Kemal Ataturk - Father of the Turkish republic.
