Michael "Mad Dog" Hertzog lived for soldiering—but he and his private army of warriors-for-hire are doing war Dog's way.

Hertzog's right hand man has vanished . . . along with $30 million of Mad Dog's money. The evidence says a trusted British merc has gone rogue, but there may be a different, more virulent form of treachery at work here. There are answers waiting aboard a train racing east from Moscow, carrying Russian gangsters, stolen Siberian diamonds, a shadow team of Iranian agents . . . and a pair of nuclear warheads. Suddenly the stakes have gotten perilously high for Mad Dog, his team, and the world . . . as time ticks rapidly away on a terrifying plot to bathe the Middle East in nuclear fire.
