Edge of Extinction

Two hundred years ago, the first dinosaur was successfully cloned. Soon after, the human race realized they'd made a colossal mistake.... The dregs of humanity have been driven into hiding, living in underground Compounds. Thirteen-year-old Sky Mundy's father was part of the inner circle of Compound leaders until five years ago, when he mysteriously disappeared. Now the time has come for Sky to try to track him down. Along with her best friend, Shawn, she steps out into the world above, a world of rampaging dinosaurs but also full of surprises.

Sky Mundy's life has changed dramatically since she fled the underground compound where she grew up. She and her friends are now prey to dinosaurs and being pursued by marines, but Sky is determined to follow a map left by her missing father. When the map leads to a hidden underwater lab, Sky is horrified to learn that scientists are still breeding dinosaurs. As she delves deeper into her father's secrets, Sky uncovers a plan that will destroy the world, unless she can put a stop to it....
