Ring and Asia Wilde's life is anything but ordinary. Some of their closest friends are endangered monkeys and rare birds. Instead of attending middle school, they accompany their parents (scientists who work to save endangered species) on adventures around the world. They spend more time climbing trees, tracking animal prints, and taking on three-hundred-pound anacondas than they do filling out worksheets. But a research trip to the Amazon rainforest turns into a dangerous mystery when their mother goes missing. Who kidnapped Dr. Jane Wilde, and why? Ring and Asia have the skills to survive the jungle—but do they have what it takes to rescue their mom?
