About the Book: Set in Raigad Fort in 1674, the kingdom is alive with anticipation for the coronation of Shivaji Maharaj—until the priceless gemstones from his sacred Bhavani Sword suddenly go missing, threatening to derail the ceremony. To avoid panic and protect the throne, the Queen Mother secretly assigns four children—Prajakta, Sarjya, Sopan, and Ganya—to uncover the truth. As they follow a trail of clues, they encounter unsettling twists: Sambhaji Raje falls mysteriously ill, a suspicious duplicate sword appears, and enemies like Aurangzeb and Adil Shah loom in the background. Racing against time, the children must solve the mystery and save the coronation before it’s too late.
