When the penguin keeper is found dead at the bottom of the penguin pool, zookeeper Madigan Amos is determined to find out what happened to him… even if it means apprehending armed intruders, getting caught in the middle of a terrorist attack, and sparring with a machete wielding murderer. The police struggle to conclude whether or not the death was accidental, but it’s not the only recent, unexplained happening at Avery Zoo. Since the tragic, avoidable death of a serval, animal rights activists have plagued the zoo. Activists with a reputation for extremism. Do they have something to do with the penguin keeper’s demise? Madi also has her suspicions about two new zoo employees, but what exactly do they have to do with the goings on? Are they activist spies, or do they have their own scores to settle? By the time Madi figures out things are not as they seem, she’s already in too deep. Someone has a hidden agenda, and they’re willing to kill to keep it a secret.
