The book is about five mighty children who were determined to save a helpless dolphin. They met dolphin accidentally but soon developed bonds of togetherness. Unlike the fearless soldiers of our country who are always ready to sacrifice their life for the well- being of humanity, the children were always ready to ‘Do and Die’ for the welfare of dolphin. The children were united and were firm in taking any decision. At last, the situation was controlled, and things were resolved peacefully.
