CHERUB agents are highly trained, extremely talented--and all under the age of seventeen. For official purposes, these agents do not exist. They are sent out on missions to spy on terrorists, hack into crucial documents, and gather intel on global threats--all without gadgets or weapons. It is an extremely dangerous job, but these agents have one crucial advantage: Adults never suspect that teens are spying on them.

In Man vs. Beast, CHERUB agents find themselves in ethical crisis. Mainstream animal protection groups have always stayed within the law, but a new band of radical liberationists argues that if humans and animals are equal, then it's right to kill or threaten one human in order to save the lives of many animals. In a new mission, James and the other CHERUB agents must go up against the most radical group yet in a daring and violent attempt to save hundreds of lives...including their own.
