Perfect for fans of Jurassic Park and Jurassic World! Code Name Flood is the electrifying sequel to The Ark Plan, which School Library Journal praised by saying: “Nonstop action, marauding dinosaurs, and kids on the run: What’s not to like?” Last week, twelve-year-old Sky found a cryptic message from her dad, who mysteriously fled the safety of their underground compound five years ago. The note said the fate of the world depended on her going topside, to a lost world that’s ruled by dinosaurs. Today, after a treacherous journey through the wilderness, Sky and her friends have made it to their destination: Lake Michigan. There they discover a hidden underwater lab, and with the help of its scientists, Sky will finally learn the truth about her father’s secret mission. Tomorrow, it will be up to Sky and her friends to save humanity from the very edge of extinction. Readers who enjoy middle grade adventures by Brandon Mull and Rick Riordan will love this action-packed story, which takes the premise of Michael Crichton’s bestselling classic to a whole new level, envisioning a postapocalyptic future where cloned dinosaurs have taken over and the world’s only hope is one group of courageous kids. But what Sky discovers in the lab is more dangerous than any dinosaur. Can a group of kids really stop an extinction-level event? Fast-Paced Action: From escaping carnivorous dinosaurs to infiltrating a top-secret facility, Sky and her friends are in a constant race against time. Unlikely Heroes: She's a girl who grew up underground. They're her only friends. The fate of the entire world rests on their shoulders. Cloned Dinosaurs: Experience a world where carnotaurs hunt in the grasslands, prehistoric sea monsters rule the lakes, and a stampeding herd is the least of your worries. A Secret Underwater Lab: Deep beneath Lake Michigan lies the Lincoln Lab, a place with its own dangerous secrets and the shocking truth about Sky’s missing father.
