Exile (Marc Dane #2) by James Swallow
A vicious Serbian gang whose profits come from fake nuclear weapons
A disgraced Russian general, with access to the real thing.
A vengeful Somali warlord, with a cause for which he’d let the world burn.
A jaded government agency, without the information to stop him.
Only one man sees what’s coming. And even he might not be able to prevent it . . .
