Black Friday (Cherub #15) - Robert Muchamore

The fifteenth title in the number one bestselling CHERUB series!

Ryan is about to board a plane, knowing that the next twenty-four hours will change everything. His mission is to stop the biggest terrorist attack America's ever seen.

Ryan works for CHERUB, a secret organisation with one key advantage: even a trained terrorist won't suspect that a teenager is spying on them.

For official purposes, these children do not exist.
