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?
