All the elements that make a good story are in Scat by Carl Hiassen. The author includes nice kids who don't always follow authority, a few not so nine kids who turn out to be better than they seem, endangered species, very bad greedy adults and a few fools. When Nick and his classmates go on a biology field trip they have to leave early because of a wildfire but not before Nick thinks he sees an endangered Florida Panther. Others have seen it too, some want to save it while others want it to go away before their illegal oil project is discovered. Scat refers both to what one says to a cat to chase it away and the droppings of animals. Nick and his classmates and their Biology teacher Mrs. Starch are all determined to save one of the 100 or so remaining Florida Panthers. Will they succeed? No spoilers here.
