From the bestselling author of STRIKE BACK, Chris Ryan returns with a new action-packed series.

Tough enough? Smart enough? Max will require all his skills just to stay alive as a Special Forces Cadet...

A top-secret government programme needs a crack team of undercover military operators. They must have awesome levels of determination, endurance and fitness. They must be able to think on their feet. The recruits undergo the most rigorous and testing selection process the modern military can devise. And in order to operate in circumstances where adult forces would be compromised, the recruits must be under sixteen. Only a few are tough enough and smart enough to make it . . . And once out in the field, they will require all their skills just to stay alive. Which is what happens when Max Silver, Abby Asher, Lukas Channing and Sami Hakim are sent into an armed siege in an inner-city school . . .
