The Mark of Halam — Thomas Ryan

USS Ulysses: State-of-the-art nuclear submarine. Deterrent. Target.

When an Olympic medalist is the subject of an attempted assassination, former SAS trooper Jeff Bradley knows his past is once again casting a shadow over his new life. A note left by the assassin confirms his suspicions: Bradley made an enemy back in Kosovo, and the man is out for revenge. But Jeff knows the killer is not working alone: higher up the ranks sits Avni Leka, a terrorist warlord who will stop at nothing to achieve his bloody goal.

And it's not just Bradley who is under threat. A hijacking leads him to sense something bigger is being planned -- a plot that, if successful, will end thousands of innocent lives, and could light the touchpaper of global conflict.

He can't allow it to happen. But events are spiralling out of control. Bradley knows he must reach the eye of the storm before it tears his world apart.
