CHERUB: The Sleepwalker : Book 9

The ninth title in the number one bestselling CHERUB series! James is getting into trouble on campus, while Lauren has an air crash to investigate … An airliner explodes over the Atlantic leaving 345 people dead. Crash investigators suspect terrorism, but they’re getting nowhere.
A distressed twelve-year-old calls a police hotline and blames his father for the explosion. It could be a breakthrough, but there’s no hard evidence and the boy has a history of violence and emotional problems. Only CHERUB agents can unearth the truth.
They’re trained professionals with one essential advantage: adults never suspect that children are spying on them. For official purposes, these children do not exist.
