Every CHERUB agent comes from somewhere. Dante Scott still has nightmares about the death of his family, brutally murdered by a biker gang. Dante is given the chance to become a member of CHERUB, a trained professional with one essential advantage: adults never suspect that children are spying on them. But when Dante joins James and Lauren Adams on a mission to infiltrate Brigands Motorcycle Club, he's ready to use everything he's learned to get revenge...

James is recruited into CHERUB, a secret division of MI5 which consists of teenage spies. He successfully completes his training and goes on his first mission.

An airliner explodes over the Atlantic leaving 345 people dead. Crash investigators suspect terrorism, but they're getting nowhere. A distressed 12-year-old calls a police hotline and blames his father for the explosion. It could be a breakthrough, but there's no hard evidence.

The British underworld is controlled by gangs. When two of them start a turf war, violence explodes on to the streets. The police need information fast, and James Adams has the contacts to infiltrate the most dangerous gang of all. He works for Cherub. Cherubs are trained professionals, aged between ten and seventeen. They exist because criminals never suspect that kids are spying on them. For official purposes, these children do not exist.

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 critical 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.

When a new radical animal protection group argues that it is right to kill or threaten one human in order to save the lives of many animals, James and the other agents must try to stop the group from completing a violent mission.
