Query: Lost in the text

I ordered this book for my Kindle based on reviews. I am sorry I did. Without pre-existing knowledge of the country and it's political problems, I was lost. The first chapter tells about a daughter going back to visit her ailing father. That chapter was coherent and I could follow. The next chapter was a disaster because that's where I needed to have some pre-existing knowledge. I had to put the book aside. I don't know if I'll ever go back to it and probably have just wasted my money.
