A flash flood. Two kids in danger. A cry for help only a NOLO can hear. Meet the NOLO. Standing 82 feet tall and weighing 45 tons, Adam is a massive Desert NOLO. But even giants can get overwhelmed—especially when they live near five of the most popular national parks. Desperate for backup, he calls his friend Izzy. In Flood in the Desert, the second book in the award-winning NOLO series, Izzy—a jungle NOLO—arrives eager to help. But just as she gets there, Adam rushes off to answer a distress call, leaving her alone in a strange, dry world.
