Terror at the Zoo

Ellen Streater received the perfect birthday present—an overnight camp-out at the zoo. Too bad she had to invite her little brother Corey along. But as night falls in the zoo, her brother becomes the least of her worries, as they discover they're locked in the zoo with an escaped convict who's stalking their every move. Unable to run, and with no help in sight, their last chance for survival is Ellen's crazy science project on animal communication. But can they get the animals to help them in time, or will it be too late?
