Savage serpents stalk the swamp!

Ryan, Stephen, and Heather spend a lot of time in the swamp, searching for snakes. They usually find harmless garter snakes and grass snakes, and they always have a lot of fun.
        But today will be different.
        Today, they will find something they never expected. Something that they couldn't believe possible . . . not in a small, quiet town in Pennsylvania.
        But it's true. Pythons . . . real pythons . . . are on the loose!
        Even worse: they're poisonous!
        And for Ryan, Stephen, and Heather, this will be a day they won't soon forget . . . if they make it out of the swamp alive!
