The tenth title in the number one bestselling CHERUB series! James and Lauren are off to America to help train the army - and get into trouble in Las Vegas ...The world's largest urban warfare training compound stands in the desert near Las Vegas.

Forty British commandos are being hunted by an entire American battalion. But their commander has an ace up his sleeve: he plans to smuggle in ten CHERUB agents, and fight the best war game ever. CHERUB agents have one crucial advantage: adults never suspect that kids are spying on them. For official purposes, these children do not exist.
