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 a highly dangerous job, but these agents have one crucial advantage: Adults never suspect that teens are spying on them.

In Maximum Security, James’s newest mission brings him to the sun-baked desert prison Arizona Max, home to 280 child criminals. One of them is the son of a weapons dealer who has been selling U.S. missiles to terrorists. If James can get the kid, CHERUB has a chance to stop the father. Getting into the prison is easy. Breaking out is the hard part.
