Istanbul Islands have been a place of residence or visit, as it is a place where writers of letters get away from the chaos and noise of the city and find calm; some writers settle on the Islands or spend certain periods of the year here. The Islands have also been the subject of literary works with their nature, social life and a world that will serve as a basis for love stories. There are names such as Mehmet Celal and Tahsin Nahit, who are known as the “island poets” in the history of literature because they frequently include the island in their works. Described as one of the famous writers of his period, Burhan Cahit Morkaya is another writer who includes Buyukada, one of the Istanbul Islands, in his works. In Coskun Gonul, one of the first novels of the author, it is seen that Buyukada occupies an ample space as a place. The story of three young girls living in Istanbul during the First World War is the subject of the novel. The plot develops around Serap, Serap’s childhood friend Asuman and Serap’s school friend Vildan. Burhan Cahit presents the love stories of these three young girls in a way that reflects the social and cultural conditions of the period. The events in the novel take place in Istanbul, especially in districts such as Kadıkoy, Sisli and Beyoglu. Since Vildan is the only daughter of a wealthy family living in Buyukada, Buyukada occupies a prominent place in the novel with its streets, avenues, hotels, and recreation areas. While war troubles and economic difficulties manifest themselves throughout the country and in the center of Istanbul, it is seen that Buyukada hosts an active social life.
