The Ark Plan (Edge of Extinction Series, Book 1)

[Children's Fiction (Ages 8-12)]One hundred and fifty years ago, the first dinosaurs were cloned. Soon after, they replaced humans at the top of the food chain. The only way to survive was to move into underground compounds. Five years ago, Sky Mundy's father vanished from North Compound without a trace. Now she has just stumbled on a clue that not only suggests his disappearance is just the tip of an even larger mystery, but also points directly to the surface. To find her dad -- and possibly even save the world -- Sky and her best friend, Shawn, must break out of their underground home and venture topside to a land reclaimed by nature and ruled by dinosaurs. Follow the two courageous friends who must survive in a lost world that's just dangerous as they've always feared!
