Franz Werfel's Forty Days of Musa Dagh is historical novel topical to your current interest. I recommend title too as it is excellent piece of literature."They Can Live in the Desert but Nowhere Else - A History of the Armenian Genocide" by Ronald Grigor Suny.
I just started it today.
For me it was the fact that midway through the series I realized I didn't like any of the characters. I didn't care what happened to any of them. All the women were unlikeable bitches, and the men were insane. I felt like I was having to force myself to keep reading, and just got tired of it.Was it a dive in quality, an unsatisfactory ending, or were they always bad?
