One of the most pure and unblemished relation in the world is that of a brother and sister. In Hindu culture, the love of brother and sister is expressed by tying ‘Raksha’ (A cotton thread) on the ‘Rakshabandhan Day’. Those who are not brother and sister by blood relation also tie rakhi and express the purity of their relationship. The word ‘Raksha’ also mean to protect or to shield.

This novel, entitled as ‘Raksha’ tells a story about such relationship. Ami is a young, idealistic, collegian girl and Shashank believes her as her sister. With the passage of time, Shashank’s mind gets changed and he no longer sees Ami as his sister. Ami on the other side continues to believe him as his brother.

Ami also encounters two people with altogether different personality – Narang, her dance teacher and Sachchidanand, her Yoga teacher. They two depict good and bad side of human mind. Narang’s mind is filled with filthiness while Sachchidanand see his late daughter in Ami and hence has special love and affection.

Will Ami change her mind or will she succeed in changing Shashank’s mind? What will happen to her brother-sister relationship with Shashank?
