I'm looking for some good (high-quality) but easy-to-read political science and cultural studies books for an EFL (English as a Foreign Language) class. Thought I would post here as well to attract any teachers, students, etc.

Although I have read several political science books before, during, and after my studies, most of them would probably be too advanced for non-native speakers.

Does anyone have any good ideas for political science/cultural studies books that would be appropriate for an upper-intermediate ESL class interested in the subject?
