A failed assassination. A dead civilian. A conspiracy moving across Europe.

Charlie Cooper is in Salzburg to oversee the final stage of a new recruit's training for Group Fifteen. Her mission is simple: eliminate a low-level trafficker involved in modern slavery. But the operation goes wrong.

A professional security team appears from nowhere. The recruit barely escapes, and an innocent bystander is killed in the chaos. The recruit swears she didn't fire the fatal shot, but one round is missing from her weapon.

When the recruit is cast out of the Group, she returns to Salzburg determined to prove the truth. Cooper follows, only to discover that the trafficker is part of something far more dangerous: a covert Russian operation to smuggle killers into Britain.

Now Cooper and the recruit must go undercover to stop the cargo before it reaches UK soil.

And this time, failure won't just end a career. It could cost dozens of lives.

Fast, ruthless, and packed with twists, Cargo is a razor-sharp Charlie Cooper thriller.
