Salaam,

Though the above mentioned recommendations have been made by Position Holders but I would still like to suggest a very good book on Principles of Political Science.

Modern Principles of Political Science - J. C. Jouhari (Indian Writer)

Positive Points:
1) The book is precice, composed over 800+ pages with a big font. So it's clear to read.

2) It is very simple.

3) It is very elaborate.

4) It contains nearly everything that the CSS syllabus demands.

5) It is stuffed with very good quotations.

6) It contains realtime examples.

That's all anybody would need to score well.

Regards,
Adil Memon
