When eleven-year-old Dev’s father dies, he can’t stop lashing out at those he loves. Until he meets Sanjay, a sprite-like being who claims there is a battle raging inside Dev’s own body. Sanjay embarks on a perilous journey beginning in the darkest realm at the bottom of Dev’s spine. As he searches for the noble warrior Prince Arjun, the only hope to defeat wicked Prince Ego, Sanjay encounters starving mobs, thieving gangs, water worlds and lands of fire, until at last he finds Arjun on the battlefield, ready to fight for Dev. This book takes the epic battle within the Gita and transports it inside the body of a young boy called Dev.
