As far as political science books go, highly recommend this one! It does a wonderful job of breaking down the various facets/causes of the Bangladeshi independence movement and the humanitarian crisis that resulted from it. The book takes a thematic approach that is roughly in chronological order, so each chapter feels isolated (read, digestible/manageable) while still being relevant to the overall message of the book.

If you have any interest in the subject, def a good read!
