Boundless Solitude tells the story of Handan Sarp, a soprano at the Istanbul City Opera who has struggled throughout her life to come to terms with her lesbianism in a society that shuns the open expression of female queerness. The novel is constructed as a series of vignettes, which highlight the nature of memory as a means of reconstructing the past. Sarp is a woman whose future holds no hope and whose life is shaped by the loneliness that results from her inner struggles as a lesbian in the restrictive social environment of Istanbul.
