The Beast With Nine Billion feet

It is 2040 A.D. The place is Pune, India. The future is here and now. Liquid computers. Flawless Skin. Emotional cars. Ilusion pods. Synthetic life. It's a world of great peril. And possibility! But not for thirteen-year-old Tara and her elder brother Aditya. Tara is stuck waiting. Waiting for her long-lost father to return, waiting to escape her aunt's fussing, waiting to leave boring old Pune, waiting to grow up. Aditya has given up on waiting. He takes what he wants and keeps what he finds. One day, everything changes when Tara bumps into a very ugly tree, two cool new friends-- Ria and Francis-- and their strange mother, Mandira. One day, everything changes when Aditya keeps something he shouldn't have found. What does Mandira want? Why are Ria and Francis so startled by the star-filled night sky? How did Tara's father become a terrorist to some but a savior to others? And just what exactly is the Beast With Nine Billion Feet?
