Cherub: Killing

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 The Killing, James is assigned to what looks like a routine mission. Leon is a small-time crook with big money. James's job is to make nice with Leon's kids, dig up some leads, and infiltrate his home. But when James suddenly unravels a much larger plot, the mission becomes anything but ordinary. Unfortunately, the only person who might know the truth is a reclusive eighteen-year-old boy—who happens to have died more than a year ago.
