Revenge Instinct?

More about the book

"We spoil ourselves with scruples long as things go well." Families are all different, and when families are in danger, all of them react differently. When the Chauhan family's loyal employee, Shiva Apte is attacked, the balance of the family shifts, towards something new. There is history that no one remembers, or no one is allowed to, and with Shiva Apte's death, all of them threaten to come spilling out onto the open. Families are forever, but the secret that ties the Chauhans, their rivals the Mehras, and their most loyal servant, Shiva, might just break them all apart.
