What would you do for a million dollars?

Now what would you do for a billion?

Back in the 1980s, as the Soviet Union collapsed, Dimitri Semenov battled Russia's fearsome mafia, and the KGB, to amass a vast fortune.

Then, as his enemies circled, he fled to America, taking his billions with him.

Now someone wants all that money back, with interest, and they'll go to any lengths to get it.

But ex-military bodyguard Ryan Lock and his partner, US Marine Ty Johnson, have other ideas.

Award-winning author Sean Black returns with a thriller that's bursting with his trademark mastery of action and suspense.

Strap yourself in! You are in for a treat!
