This adventure story should appeal to kids who are "into" animals and love adventure. Zoe and Ben are a brother and sister who work for their Uncle Stephen, who runs an international wildlife-rescue mission and owns all sorts of cool technological gadgets. He sends them all over the world to save endangered animals, and in this story he has sent them to the Himalayas to save a snow leopard and her three cubs who are in danger of being poisoned by villagers whose have lost livestock to the leopards. We follow Zoe and Ben through every kind of danger ... from the danger of being eaten by the leopards themselves, being hunted by the villagers, to the danger of being killed by an enormous snow avalanche. Then there is also the matter of altitude sickness to contend with. The sentences are short and the adventure comes at you rat-a-tat. But on page 138, the authors have written "Moonlight shined down upon the snow" and that really bothered me. It should have been "Moonlight shone down".
