Red Sonja: Empire of the Damned by Steve Niles

After landing in jail following a night of drunken revelry, Red Sonja hears an outlandish story from a fellow inmate. Deep in the mountains lies a dead city in a valley with no name. Abandoned and forgotten, its fields and streets are littered with the bones of two armies, all destroyed by a curse from a warlock who has long since vanished, along with his vast treasure - untold riches just waiting to be taken. At least that is the legend. But Sonja's cellmate Morgo has more than a diverting tale - he's also got a map that says this legend could well be reality. All they need to do is break out of lockup and hit the road - which may be easier said than done!
