Regarding RSS (Rastriya Swayamsevak Sangh) there are plenty of books from either a supporter or a person opposing the RSS. This is from a RSS member who is inclined to introduce the Sangh (the name RSS is otherwise called) in a very simple form. Generally speaking, reading a non-fiction is dry for a general reader. But this book is a easy read since the language used is very simple and there are about 10 interesting stories sprinkled in between.
