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. Perfect for fans of Brandon Mull, Lisa McMann, and Rick Riordan, this exhilarating debut novel follows two courageous friends who must survive in a lost world that’s as dangerous as they’ve always feared but also unlike anything they could ever have imagined. “As a budding Katniss Everdeen—tough, stubborn, resilient, and though new to the bow a quick enough learner by the end to put an arrow through the eye of a ravening spinosaurus—Sky makes a promising protagonist.” - Kirkus Reviews “This gripping survival adventure offers readers a potent mix of creative setting, edge-of-your-seat plotting, and admirable heroes. The world building is particularly strong, balancing the campy, the terrifying, and the dystopian, with plenty of engaging details like dinosaur pets and a treehouse worthy of the Swiss Family Robinson. Sky and friends are equally appealing, bringing their own strengths and foibles to the mix. Perfect for readers who have carried their love of dinosaurs into middle school, the novel is also a strong fit for readers who want dystopias but aren’t quite ready for the bleakness of The Hunger Games. Unresolved mysteries and a few surprising last-minute reveals leave plenty for the adventurers to learn in expected sequels and will leave readers hungry for more.” - Bulletin of the Center for Children’s Books “This gripping survival adventure offers readers a potent mix of creative setting, edge-of-your-seat plotting, and admirable heroes.
